DESCRIPTION

You can query/set/replace/unset options with this command. The name is actually the section and the key separated by a dot, and the value will be escaped.

Multiple lines can be added to an option by using the --add option. If you want to update or unset an option which can occur on multiple lines, a POSIX regexp value_regex needs to be given. Only the existing values that match the regexp are updated or unset. If you want to handle the lines that do not match the regex, just prepend a single exclamation mark in front (see also the section called “EXAMPLES”).

The type specifier can be either --int or --bool, to make git config ensure that the variable(s) are of the given type and convert the value to the canonical form (simple decimal number for int, a "true" or "false" string for bool), or --path, which does some path expansion (see --path below). If no type specifier is passed, no checks or transformations are performed on the value.

When reading, the values are read from the system, global and repository local configuration files by default, and options --system, --global, --local and --file <filename> can be used to tell the command to read from only that location (see the section called “FILES”).

When writing, the new value is written to the repository local configuration file by default, and options --system, --global, --file <filename> can be used to tell the command to write to that location (you can say --local but that is the default).

This command will fail with non-zero status upon error. Some exit codes are:

    1. The config file is invalid (ret=3),

    2. can not write to the config file (ret=4),

    3. no section or name was provided (ret=2),

    4. the section or key is invalid (ret=1),

    5. you try to unset an option which does not exist (ret=5),

    6. you try to unset/set an option for which multiple lines match (ret=5), or

    7. you try to use an invalid regexp (ret=6).

On success, the command returns the exit code 0.

OPTIONS

--replace-all
    Default behavior is to replace at most one line. This replaces all lines matching the key (and optionally the value_regex).

--add
    Adds a new line to the option without altering any existing values. This is the same as providing ^$ as the value_regex in --replace-all.

--get
    Get the value for a given key (optionally filtered by a regex matching the value). Returns error code 1 if the key was not found and the last value if multiple key values were found.

--get-all
    Like get, but does not fail if the number of values for the key is not exactly one.

--get-regexp
    Like --get-all, but interprets the name as a regular expression and writes out the key names. Regular expression matching is currently case-sensitive and done against a canonicalized version of the key in which section and variable names are lowercased, but subsection names are not.

--get-urlmatch name URL
    When given a two-part name section.key, the value for section.<url>.key whose <url> part matches the best to the given URL is returned (if no such key exists, the value for section.key is used as a fallback). When given just the section as name, do so for all the keys in the section and list them.

--global
    For writing options: write to global ~/.gitconfig file rather than the repository .git/config, write to $XDG_CONFIG_HOME/git/config file if this file exists and the ~/.gitconfig file doesn’t.

    For reading options: read only from global ~/.gitconfig and from $XDG_CONFIG_HOME/git/config rather than from all available files.

    See also the section called “FILES”.

--system
    For writing options: write to system-wide $(prefix)/etc/gitconfig rather than the repository .git/config.

    For reading options: read only from system-wide $(prefix)/etc/gitconfig rather than from all available files.

    See also the section called “FILES”.

--local
    For writing options: write to the repository .git/config file. This is the default behavior.

    For reading options: read only from the repository .git/config rather than from all available files.

    See also the section called “FILES”.

-f config-file, --file config-file
    Use the given config file instead of the one specified by GIT_CONFIG.

--blob blob
    Similar to --file but use the given blob instead of a file. E.g. you can use master:.gitmodules to read values from the file .gitmodules in the master branch. See "SPECIFYING REVISIONS" section in gitrevisions(7) for a more complete list of ways to spell blob names.

--remove-section
    Remove the given section from the configuration file.

--rename-section
    Rename the given section to a new name.

--unset
    Remove the line matching the key from config file.

--unset-all
    Remove all lines matching the key from config file.

-l, --list
    List all variables set in config file.

--bool
    git config will ensure that the output is "true" or "false"

--int
    git config will ensure that the output is a simple decimal number. An optional value suffix of k, m, or g in the config file will cause the value to be multiplied by 1024, 1048576, or 1073741824 prior to output.

--bool-or-int
    git config will ensure that the output matches the format of either --bool or --int, as described above.

--path
    git-config will expand leading ~ to the value of $HOME, and ~user to the home directory for the specified user. This option has no effect when setting the value (but you can use git config bla ~/ from the command line to let your shell do the expansion).

-z, --null
    For all options that output values and/or keys, always end values with the null character (instead of a newline). Use newline instead as a delimiter between key and value. This allows for secure parsing of the output without getting confused e.g. by values that contain line breaks.

--get-colorbool name [stdout-is-tty]
    Find the color setting for name (e.g. color.diff) and output "true" or "false". stdout-is-tty should be either "true" or "false", and is taken into account when configuration says "auto". If stdout-is-tty is missing, then checks the standard output of the command itself, and exits with status 0 if color is to be used, or exits with status 1 otherwise. When the color setting for name is undefined, the command uses color.ui as fallback.

--get-color name [default]
    Find the color configured for name (e.g. color.diff.new) and output it as the ANSI color escape sequence to the standard output. The optional default parameter is used instead, if there is no color configured for name.

-e, --edit
    Opens an editor to modify the specified config file; either --system, --global, or repository (default).

--[no-]includes
    Respect include.* directives in config files when looking up values. Defaults to on.

FILES

If not set explicitly with --file, there are four files where git config will search for configuration options:

$(prefix)/etc/gitconfig
    System-wide configuration file.

$XDG_CONFIG_HOME/git/config
    Second user-specific configuration file. If $XDG_CONFIG_HOME is not set or empty, $HOME/.config/git/config will be used. Any single-valued variable set in this file will be overwritten by whatever is in ~/.gitconfig. It is a good idea not to create this file if you sometimes use older versions of Git, as support for this file was added fairly recently.

~/.gitconfig
    User-specific configuration file. Also called "global" configuration file.

$GIT_DIR/config
    Repository specific configuration file.

If no further options are given, all reading options will read all of these files that are available. If the global or the system-wide configuration file are not available they will be ignored. If the repository configuration file is not available or readable, git config will exit with a non-zero error code. However, in neither case will an error message be issued.

The files are read in the order given above, with last value found taking precedence over values read earlier. When multiple values are taken then all values of a key from all files will be used.

All writing options will per default write to the repository specific configuration file. Note that this also affects options like --replace-all and --unset. git config will only ever change one file at a time.

You can override these rules either by command line options or by environment variables. The --global and the --system options will limit the file used to the global or system-wide file respectively. The GIT_CONFIG environment variable has a similar effect, but you can specify any filename you want.

ENVIRONMENT

GIT_CONFIG
    Take the configuration from the given file instead of .git/config. Using the "--global" option forces this to ~/.gitconfig. Using the "--system" option forces this to $(prefix)/etc/gitconfig.

GIT_CONFIG_NOSYSTEM
    Whether to skip reading settings from the system-wide $(prefix)/etc/gitconfig file. See git(1) for details.

See also the section called “FILES”.

EXAMPLES

Given a .git/config like this:

    #
    # This is the config file, and
    # a '#' or ';' character indicates
    # a comment
    #

    ; core variables
    [core]
            ; Don't trust file modes
            filemode = false

    ; Our diff algorithm
    [diff]
            external = /usr/local/bin/diff-wrapper
            renames = true

    ; Proxy settings
    [core]
            gitproxy=proxy-command for kernel.org
            gitproxy=default-proxy ; for all the rest

    ; HTTP
    [http]
            sslVerify
    [http "https://weak.example.com"]
            sslVerify = false
            cookieFile = /tmp/cookie.txt

you can set the filemode to true with

    % git config core.filemode true

The hypothetical proxy command entries actually have a postfix to discern what URL they apply to. Here is how to change the entry for kernel.org to "ssh".

    % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'

This makes sure that only the key/value pair for kernel.org is replaced.

To delete the entry for renames, do

    % git config --unset diff.renames

If you want to delete an entry for a multivar (like core.gitproxy above), you have to provide a regex matching the value of exactly one line.

To query the value for a given key, do

    % git config --get core.filemode

or

    % git config core.filemode

or, to query a multivar:

    % git config --get core.gitproxy "for kernel.org$"

If you want to know all the values for a multivar, do:

    % git config --get-all core.gitproxy

If you like to live dangerously, you can replace all core.gitproxy by a new one with

    % git config --replace-all core.gitproxy ssh

However, if you really only want to replace the line for the default proxy, i.e. the one without a "for ..." postfix, do something like this:

    % git config core.gitproxy ssh '! for '

To actually match only values with an exclamation mark, you have to

    % git config section.key value '[!]'

To add a new proxy, without altering any of the existing ones, use

    % git config --add core.gitproxy '"proxy-command" for example.com'

An example to use customized color from the configuration in your script:

    #!/bin/sh
    WS=$(git config --get-color color.diff.whitespace "blue reverse")
    RESET=$(git config --get-color "" "reset")
    echo "${WS}your whitespace color or blue reverse${RESET}"

For URLs in https://weak.example.com, http.sslVerify is set to false, while it is set to true for all others:

    % git config --bool --get-urlmatch http.sslverify https://good.example.com
    true
    % git config --bool --get-urlmatch http.sslverify https://weak.example.com
    false
    % git config --get-urlmatch http https://weak.example.com
    http.cookiefile /tmp/cookie.txt
    http.sslverify false

CONFIGURATION FILE

The Git configuration file contains a number of variables that affect the Git commands' behavior. The .git/config file in each repository is used to store the configuration for that repository, and $HOME/.gitconfig is used to store a per-user configuration as fallback values for the .git/config file. The file /etc/gitconfig can be used to store a system-wide default configuration.

The configuration variables are used by both the Git plumbing and the porcelains. The variables are divided into sections, wherein the fully qualified variable name of the variable itself is the last dot-separated segment and the section name is everything before the last dot. The variable names are case-insensitive, allow only alphanumeric characters and -, and must start with an alphabetic character. Some variables may appear multiple times.

  Syntax

The syntax is fairly flexible and permissive; whitespaces are mostly ignored. The # and ; characters begin comments to the end of line, blank lines are ignored.

The file consists of sections and variables. A section begins with the name of the section in square brackets and continues until the next section begins. Section names are not case sensitive. Only alphanumeric characters, - and . are allowed in section names. Each variable must belong to some section, which means that there must be a section header before the first setting of a variable.

Sections can be further divided into subsections. To begin a subsection put its name in double quotes, separated by space from the section name, in the section header, like in the example below:

            [section "subsection"]

Subsection names are case sensitive and can contain any characters except newline (doublequote " and backslash have to be escaped as \" and \\, respectively). Section headers cannot span multiple lines. Variables may belong directly to a section or to a given subsection. You can have [section] if you have [section "subsection"], but you don’t need to.

There is also a deprecated [section.subsection] syntax. With this syntax, the subsection name is converted to lower-case and is also compared case sensitively. These subsection names follow the same restrictions as section names.

All the other lines (and the remainder of the line after the section header) are recognized as setting variables, in the form name = value. If there is no equal sign on the line, the entire line is taken as name and the variable is recognized as boolean "true". The variable names are case-insensitive, allow only alphanumeric characters and -, and must start with an alphabetic character. There can be more than one value for a given variable; we say then that the variable is multivalued.

Leading and trailing whitespace in a variable value is discarded. Internal whitespace within a variable value is retained verbatim.

The values following the equals sign in variable assign are all either a string, an integer, or a boolean. Boolean values may be given as yes/no, 1/0, true/false or on/off. Case is not significant in boolean values, when converting value to the canonical form using --bool type specifier; git config will ensure that the output is "true" or "false".

String values may be entirely or partially enclosed in double quotes. You need to enclose variable values in double quotes if you want to preserve leading or trailing whitespace, or if the variable value contains comment characters (i.e. it contains # or ;). Double quote " and backslash \ characters in variable values must be escaped: use \" for " and \\ for \.

The following escape sequences (beside \" and \\) are recognized: \n for newline character (NL), \t for horizontal tabulation (HT, TAB) and \b for backspace (BS). Other char escape sequences (including octal escape sequences) are invalid.

Variable values ending in a \ are continued on the next line in the customary UNIX fashion.

Some variables may require a special value format.

  Includes

You can include one config file from another by setting the special include.path variable to the name of the file to be included. The included file is expanded immediately, as if its contents had been found at the location of the include directive. If the value of the include.path variable is a relative path, the path is considered to be relative to the configuration file in which the include directive was found. The value of include.path is subject to tilde expansion: ~/ is expanded to the value of $HOME, and ~user/ to the specified user’s home directory. See below for examples.

  Example

    # Core variables
    [core]
            ; Don't trust file modes
            filemode = false

    # Our diff algorithm
    [diff]
            external = /usr/local/bin/diff-wrapper
            renames = true

    [branch "devel"]
            remote = origin
            merge = refs/heads/devel

    # Proxy settings
    [core]
            gitProxy="ssh" for "kernel.org"
            gitProxy=default-proxy ; for the rest

    [include]
            path = /path/to/foo.inc ; include by absolute path
            path = foo ; expand "foo" relative to the current file
            path = ~/foo ; expand "foo" in your $HOME directory

  Variables

Note that this list is non-comprehensive and not necessarily complete. For command-specific variables, you will find a more detailed description in the appropriate manual page. You will find a description of non-core porcelain configuration variables in the respective porcelain documentation.

advice.*
    These variables control various optional help messages designed to aid new users. All advice.* variables default to true, and you can tell Git that you do not need help by setting these to false:

    pushUpdateRejected
        Set this variable to false if you want to disable pushNonFFCurrent, pushNonFFDefault, pushNonFFMatching, pushAlreadyExists, pushFetchFirst, and pushNeedsForce simultaneously.

    pushNonFFCurrent
        Advice shown when git-push(1) fails due to a non-fast-forward update to the current branch.

    pushNonFFDefault
        Advice to set push.default to upstream or current when you ran git-push(1) and pushed matching refs by default (i.e. you did not provide an explicit refspec, and no push.default configuration was set) and it resulted in a non-fast-forward error.

    pushNonFFMatching
        Advice shown when you ran git-push(1) and pushed matching refs explicitly (i.e. you used :, or specified a refspec that isn’t your current branch) and it resulted in a non-fast-forward error.

    pushAlreadyExists
        Shown when git-push(1) rejects an update that does not qualify for fast-forwarding (e.g., a tag.)

    pushFetchFirst
        Shown when git-push(1) rejects an update that tries to overwrite a remote ref that points at an object we do not have.

    pushNeedsForce
        Shown when git-push(1) rejects an update that tries to overwrite a remote ref that points at an object that is not a commit-ish, or make the remote ref point at an object that is not a commit-ish.

    statusHints
        Show directions on how to proceed from the current state in the output of git-status(1), in the template shown when writing commit messages in git-commit(1), and in the help message shown by git-checkout(1) when switching branch.

    statusUoption
        Advise to consider using the -u option to git-status(1) when the command takes more than 2 seconds to enumerate untracked files.

    commitBeforeMerge
        Advice shown when git-merge(1) refuses to merge to avoid overwriting local changes.

    resolveConflict
        Advice shown by various commands when conflicts prevent the operation from being performed.

    implicitIdentity
        Advice on how to set your identity configuration when your information is guessed from the system username and domain name.

    detachedHead
        Advice shown when you used git-checkout(1) to move to the detach HEAD state, to instruct how to create a local branch after the fact.

    amWorkDir
        Advice that shows the location of the patch file when git-am(1) fails to apply it.

    rmHints
        In case of failure in the output of git-rm(1), show directions on how to proceed from the current state.

core.fileMode
    If false, the executable bit differences between the index and the working tree are ignored; useful on broken filesystems like FAT. See git-update-index(1).

    The default is true, except git-clone(1) or git-init(1) will probe and set core.fileMode false if appropriate when the repository is created.

core.ignorecase
    If true, this option enables various workarounds to enable Git to work better on filesystems that are not case sensitive, like FAT. For example, if a directory listing finds "makefile" when Git expects "Makefile", Git will assume it is really the same file, and continue to remember it as "Makefile".

    The default is false, except git-clone(1) or git-init(1) will probe and set core.ignorecase true if appropriate when the repository is created.

core.precomposeunicode
    This option is only used by Mac OS implementation of Git. When core.precomposeunicode=true, Git reverts the unicode decomposition of filenames done by Mac OS. This is useful when sharing a repository between Mac OS and Linux or Windows. (Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7). When false, file names are handled fully transparent by Git, which is backward compatible with older versions of Git.

core.trustctime
    If false, the ctime differences between the index and the working tree are ignored; useful when the inode change time is regularly modified by something outside Git (file system crawlers and some backup systems). See git-update-index(1). True by default.

core.checkstat
    Determines which stat fields to match between the index and work tree. The user can set this to default or minimal. Default (or explicitly default), is to check all fields, including the sub-second part of mtime and ctime.

core.quotepath
    The commands that output paths (e.g. ls-files, diff), when not given the -z option, will quote "unusual" characters in the pathname by enclosing the pathname in a double-quote pair and with backslashes the same way strings in C source code are quoted. If this variable is set to false, the bytes higher than 0x80 are not quoted but output as verbatim. Note that double quote, backslash and control characters are always quoted without -z regardless of the setting of this variable.

core.eol
    Sets the line ending type to use in the working directory for files that have the text property set. Alternatives are lf, crlf and native, which uses the platform’s native line ending. The default value is native. See gitattributes(5) for more information on end-of-line conversion.

core.safecrlf
    If true, makes Git check if converting CRLF is reversible when end-of-line conversion is active. Git will verify if a command modifies a file in the work tree either directly or indirectly. For example, committing a file followed by checking out the same file should yield the original file in the work tree. If this is not the case for the current setting of core.autocrlf, Git will reject the file. The variable can be set to "warn", in which case Git will only warn about an irreversible conversion but continue the operation.

    CRLF conversion bears a slight chance of corrupting data. When it is enabled, Git will convert CRLF to LF during commit and LF to CRLF during checkout. A file that contains a mixture of LF and CRLF before the commit cannot be recreated by Git. For text files this is the right thing to do: it corrects line endings such that we have only LF line endings in the repository. But for binary files that are accidentally classified as text the conversion can corrupt data.

    If you recognize such corruption early you can easily fix it by setting the conversion type explicitly in .gitattributes. Right after committing you still have the original file in your work tree and this file is not yet corrupted. You can explicitly tell Git that this file is binary and Git will handle the file appropriately.

    Unfortunately, the desired effect of cleaning up text files with mixed line endings and the undesired effect of corrupting binary files cannot be distinguished. In both cases CRLFs are removed in an irreversible way. For text files this is the right thing to do because CRLFs are line endings, while for binary files converting CRLFs corrupts data.

    Note, this safety check does not mean that a checkout will generate a file identical to the original file for a different setting of core.eol and core.autocrlf, but only for the current one. For example, a text file with LF would be accepted with core.eol=lf and could later be checked out with core.eol=crlf, in which case the resulting file would contain CRLF, although the original file contained LF. However, in both work trees the line endings would be consistent, that is either all LF or all CRLF, but never mixed. A file with mixed line endings would be reported by the core.safecrlf mechanism.

core.autocrlf
    Setting this variable to "true" is almost the same as setting the text attribute to "auto" on all files except that text files are not guaranteed to be normalized: files that contain CRLF in the repository will not be touched. Use this setting if you want to have CRLF line endings in your working directory even though the repository does not have normalized line endings. This variable can be set to input, in which case no output conversion is performed.

core.symlinks
    If false, symbolic links are checked out as small plain files that contain the link text. git-update-index(1) and git-add(1) will not change the recorded type to regular file. Useful on filesystems like FAT that do not support symbolic links.

    The default is true, except git-clone(1) or git-init(1) will probe and set core.symlinks false if appropriate when the repository is created.

core.gitProxy
    A "proxy command" to execute (as command host port) instead of establishing direct connection to the remote server when using the Git protocol for fetching. If the variable value is in the "COMMAND for DOMAIN" format, the command is applied only on hostnames ending with the specified domain string. This variable may be set multiple times and is matched in the given order; the first match wins.

    Can be overridden by the GIT_PROXY_COMMAND environment variable (which always applies universally, without the special "for" handling).

    The special string none can be used as the proxy command to specify that no proxy be used for a given domain pattern. This is useful for excluding servers inside a firewall from proxy use, while defaulting to a common proxy for external domains.

core.ignoreStat
    If true, commands which modify both the working tree and the index will mark the updated paths with the "assume unchanged" bit in the index. These marked files are then assumed to stay unchanged in the working tree, until you mark them otherwise manually - Git will not detect the file changes by lstat() calls. This is useful on systems where those are very slow, such as Microsoft Windows. See git-update-index(1). False by default.

core.preferSymlinkRefs
    Instead of the default "symref" format for HEAD and other symbolic reference files, use symbolic links. This is sometimes needed to work with old scripts that expect HEAD to be a symbolic link.

core.bare
    If true this repository is assumed to be bare and has no working directory associated with it. If this is the case a number of commands that require a working directory will be disabled, such as git-add(1) or git-merge(1).

    This setting is automatically guessed by git-clone(1) or git-init(1) when the repository was created. By default a repository that ends in "/.git" is assumed to be not bare (bare = false), while all other repositories are assumed to be bare (bare = true).

core.worktree
    Set the path to the root of the working tree. This can be overridden by the GIT_WORK_TREE environment variable and the --work-tree command line option. The value can be an absolute path or relative to the path to the .git directory, which is either specified by --git-dir or GIT_DIR, or automatically discovered. If --git-dir or GIT_DIR is specified but none of --work-tree, GIT_WORK_TREE and core.worktree is specified, the current working directory is regarded as the top level of your working tree.

    Note that this variable is honored even when set in a configuration file in a ".git" subdirectory of a directory and its value differs from the latter directory (e.g. "/path/to/.git/config" has core.worktree set to "/different/path"), which is most likely a misconfiguration. Running Git commands in the "/path/to" directory will still use "/different/path" as the root of the work tree and can cause confusion unless you know what you are doing (e.g. you are creating a read-only snapshot of the same index to a location different from the repository’s usual working tree).

core.logAllRefUpdates
    Enable the reflog. Updates to a ref <ref> is logged to the file "$GIT_DIR/logs/<ref>", by appending the new and old SHA-1, the date/time and the reason of the update, but only when the file exists. If this configuration variable is set to true, missing "$GIT_DIR/logs/<ref>" file is automatically created for branch heads (i.e. under refs/heads/), remote refs (i.e. under refs/remotes/), note refs (i.e. under refs/notes/), and the symbolic ref HEAD.

    This information can be used to determine what commit was the tip of a branch "2 days ago".

    This value is true by default in a repository that has a working directory associated with it, and false by default in a bare repository.

core.repositoryFormatVersion
    Internal variable identifying the repository format and layout version.

core.sharedRepository
    When group (or true), the repository is made shareable between several users in a group (making sure all the files and objects are group-writable). When all (or world or everybody), the repository will be readable by all users, additionally to being group-shareable. When umask (or false), Git will use permissions reported by umask(2). When 0xxx, where 0xxx is an octal number, files in the repository will have this mode value. 0xxx will override user’s umask value (whereas the other options will only override requested parts of the user’s umask value). Examples: 0660 will make the repo read/write-able for the owner and group, but inaccessible to others (equivalent to group unless umask is e.g. 0022). 0640 is a repository that is group-readable but not group-writable. See git-init(1). False by default.

core.warnAmbiguousRefs
    If true, Git will warn you if the ref name you passed it is ambiguous and might match multiple refs in the repository. True by default.

core.compression
    An integer -1..9, indicating a default compression level. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If set, this provides a default to other compression variables, such as core.loosecompression and pack.compression.

core.loosecompression
    An integer -1..9, indicating the compression level for objects that are not in a pack file. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If not set, defaults to core.compression. If that is not set, defaults to 1 (best speed).

core.packedGitWindowSize
    Number of bytes of a pack file to map into memory in a single mapping operation. Larger window sizes may allow your system to process a smaller number of large pack files more quickly. Smaller window sizes will negatively affect performance due to increased calls to the operating system’s memory manager, but may improve performance when accessing a large number of large pack files.

    Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32 MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should be reasonable for all users/operating systems. You probably do not need to adjust this value.

    Common unit suffixes of k, m, or g are supported.

core.packedGitLimit
    Maximum number of bytes to map simultaneously into memory from pack files. If Git needs to access more than this many bytes at once to complete an operation it will unmap existing regions to reclaim virtual address space within the process.

    Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms. This should be reasonable for all users/operating systems, except on the largest projects. You probably do not need to adjust this value.

    Common unit suffixes of k, m, or g are supported.

core.deltaBaseCacheLimit
    Maximum number of bytes to reserve for caching base objects that may be referenced by multiple deltified objects. By storing the entire decompressed base objects in a cache Git is able to avoid unpacking and decompressing frequently used base objects multiple times.

    Default is 16 MiB on all platforms. This should be reasonable for all users/operating systems, except on the largest projects. You probably do not need to adjust this value.

    Common unit suffixes of k, m, or g are supported.

core.bigFileThreshold
    Files larger than this size are stored deflated, without attempting delta compression. Storing large files without delta compression avoids excessive memory usage, at the slight expense of increased disk usage.

    Default is 512 MiB on all platforms. This should be reasonable for most projects as source code and other text files can still be delta compressed, but larger binary media files won’t be.

    Common unit suffixes of k, m, or g are supported.

core.excludesfile
    In addition to .gitignore (per-directory) and .git/info/exclude, Git looks into this file for patterns of files which are not meant to be tracked. "~/" is expanded to the value of $HOME and "~user/" to the specified user’s home directory. Its default value is $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/ignore is used instead. See gitignore(5).

core.askpass
    Some commands (e.g. svn and http interfaces) that interactively ask for a password can be told to use an external program given via the value of this variable. Can be overridden by the GIT_ASKPASS environment variable. If not set, fall back to the value of the SSH_ASKPASS environment variable or, failing that, a simple password prompt. The external program shall be given a suitable prompt as command line argument and write the password on its STDOUT.

core.attributesfile
    In addition to .gitattributes (per-directory) and .git/info/attributes, Git looks into this file for attributes (see gitattributes(5)). Path expansions are made the same way as for core.excludesfile. Its default value is $XDG_CONFIG_HOME/git/attributes. If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/attributes is used instead.

core.editor
    Commands such as commit and tag that lets you edit messages by launching an editor uses the value of this variable when it is set, and the environment variable GIT_EDITOR is not set. See git-var(1).

core.commentchar
    Commands such as commit and tag that lets you edit messages consider a line that begins with this character commented, and removes them after the editor returns (default #).

sequence.editor
    Text editor used by git rebase -i for editing the rebase instruction file. The value is meant to be interpreted by the shell when it is used. It can be overridden by the GIT_SEQUENCE_EDITOR environment variable. When not configured the default commit message editor is used instead.

core.pager
    Text viewer for use by Git commands (e.g., less). The value is meant to be interpreted by the shell. The order of preference is the $GIT_PAGER environment variable, then core.pager configuration, then $PAGER, and then the default chosen at compile time (usually less).

    When the LESS environment variable is unset, Git sets it to FRSX (if LESS environment variable is set, Git does not change it at all). If you want to selectively override Git’s default setting for LESS, you can set core.pager to e.g. less -+S. This will be passed to the shell by Git, which will translate the final command to LESS=FRSX less -+S. The environment tells the command to set the S option to chop long lines but the command line resets it to the default to fold long lines.

    Likewise, when the LV environment variable is unset, Git sets it to -c. You can override this setting by exporting LV with another value or setting core.pager to lv +c.

core.whitespace
    A comma separated list of common whitespace problems to notice. git diff will use color.diff.whitespace to highlight them, and git apply --whitespace=error will consider them as errors. You can prefix - to disable any of them (e.g. -trailing-space):

        • blank-at-eol treats trailing whitespaces at the end of the line as an error (enabled by default).

        • space-before-tab treats a space character that appears immediately before a tab character in the initial indent part of the line as an error (enabled by default).

        • indent-with-non-tab treats a line that is indented with space characters instead of the equivalent tabs as an error (not enabled by default).

        • tab-in-indent treats a tab character in the initial indent part of the line as an error (not enabled by default).

        • blank-at-eof treats blank lines added at the end of file as an error (enabled by default).

        • trailing-space is a short-hand to cover both blank-at-eol and blank-at-eof.

        • cr-at-eol treats a carriage-return at the end of line as part of the line terminator, i.e. with it, trailing-space does not trigger if the character before such a carriage-return is not a whitespace (not enabled by default).

        • tabwidth=<n> tells how many character positions a tab occupies; this is relevant for indent-with-non-tab and when Git fixes tab-in-indent errors. The default tab width is 8. Allowed values are 1 to 63.

core.fsyncobjectfiles
    This boolean will enable fsync() when writing object files.

    This is a total waste of time and effort on a filesystem that orders data writes properly, but can be useful for filesystems that do not use journalling (traditional UNIX filesystems) or that only journal metadata and not file contents (OS X’s HFS+, or Linux ext3 with "data=writeback").

core.preloadindex
    Enable parallel index preload for operations like git diff

    This can speed up operations like git diff and git status especially on filesystems like NFS that have weak caching semantics and thus relatively high IO latencies. With this set to true, Git will do the index comparison to the filesystem data in parallel, allowing overlapping IO’s.

core.createObject
    You can set this to link, in which case a hardlink followed by a delete of the source are used to make sure that object creation will not overwrite existing objects.

    On some file system/operating system combinations, this is unreliable. Set this config setting to rename there; However, This will remove the check that makes sure that existing object files will not get overwritten.

core.notesRef
    When showing commit messages, also show notes which are stored in the given ref. The ref must be fully qualified. If the given ref does not exist, it is not an error but means that no notes should be printed.

    This setting defaults to "refs/notes/commits", and it can be overridden by the GIT_NOTES_REF environment variable. See git-notes(1).

core.sparseCheckout
    Enable "sparse checkout" feature. See section "Sparse checkout" in git-read-tree(1) for more information.

core.abbrev
    Set the length object names are abbreviated to. If unspecified, many commands abbreviate to 7 hexdigits, which may not be enough for abbreviated object names to stay unique for sufficiently long time.

add.ignore-errors, add.ignoreErrors
    Tells git add to continue adding files when some files cannot be added due to indexing errors. Equivalent to the --ignore-errors option of git-add(1). Older versions of Git accept only add.ignore-errors, which does not follow the usual naming convention for configuration variables. Newer versions of Git honor add.ignoreErrors as well.

alias.*
    Command aliases for the git(1) command wrapper - e.g. after defining "alias.last = cat-file commit HEAD", the invocation "git last" is equivalent to "git cat-file commit HEAD". To avoid confusion and troubles with script usage, aliases that hide existing Git commands are ignored. Arguments are split by spaces, the usual shell quoting and escaping is supported. quote pair and a backslash can be used to quote them.

    If the alias expansion is prefixed with an exclamation point, it will be treated as a shell command. For example, defining "alias.new = !gitk --all --not ORIG_HEAD", the invocation "git new" is equivalent to running the shell command "gitk --all --not ORIG_HEAD". Note that shell commands will be executed from the top-level directory of a repository, which may not necessarily be the current directory. GIT_PREFIX is set as returned by running git rev-parse --show-prefix from the original current directory. See git-rev-parse(1).

am.keepcr
    If true, git-am will call git-mailsplit for patches in mbox format with parameter --keep-cr. In this case git-mailsplit will not remove \r from lines ending with \r\n. Can be overridden by giving --no-keep-cr from the command line. See git-am(1), git-mailsplit(1).

apply.ignorewhitespace
    When set to change, tells git apply to ignore changes in whitespace, in the same way as the --ignore-space-change option. When set to one of: no, none, never, false tells git apply to respect all whitespace differences. See git-apply(1).

apply.whitespace
    Tells git apply how to handle whitespaces, in the same way as the --whitespace option. See git-apply(1).

branch.autosetupmerge
    Tells git branch and git checkout to set up new branches so that git-pull(1) will appropriately merge from the starting point branch. Note that even if this option is not set, this behavior can be chosen per-branch using the --track and --no-track options. The valid settings are: false — no automatic setup is done; true — automatic setup is done when the starting point is a remote-tracking branch; always — automatic setup is done when the starting point is either a local branch or remote-tracking branch. This option defaults to true.

branch.autosetuprebase
    When a new branch is created with git branch or git checkout that tracks another branch, this variable tells Git to set up pull to rebase instead of merge (see "branch.<name>.rebase"). When never, rebase is never automatically set to true. When local, rebase is set to true for tracked branches of other local branches. When remote, rebase is set to true for tracked branches of remote-tracking branches. When always, rebase will be set to true for all tracking branches. See "branch.autosetupmerge" for details on how to set up a branch to track another branch. This option defaults to never.

branch.<name>.remote
    When on branch <name>, it tells git fetch and git push which remote to fetch from/push to. The remote to push to may be overridden with remote.pushdefault (for all branches). The remote to push to, for the current branch, may be further overridden by branch.<name>.pushremote. If no remote is configured, or if you are not on any branch, it defaults to origin for fetching and remote.pushdefault for pushing. Additionally, . (a period) is the current local repository (a dot-repository), see branch.<name>.merge's final note below.

branch.<name>.pushremote
    When on branch <name>, it overrides branch.<name>.remote for pushing. It also overrides remote.pushdefault for pushing from branch <name>. When you pull from one place (e.g. your upstream) and push to another place (e.g. your own publishing repository), you would want to set remote.pushdefault to specify the remote to push to for all branches, and use this option to override it for a specific branch.

branch.<name>.merge
    Defines, together with branch.<name>.remote, the upstream branch for the given branch. It tells git fetch/git pull/git rebase which branch to merge and can also affect git push (see push.default). When in branch <name>, it tells git fetch the default refspec to be marked for merging in FETCH_HEAD. The value is handled like the remote part of a refspec, and must match a ref which is fetched from the remote given by "branch.<name>.remote". The merge information is used by git pull (which at first calls git fetch) to lookup the default branch for merging. Without this option, git pull defaults to merge the first refspec fetched. Specify multiple values to get an octopus merge. If you wish to setup git pull so that it merges into <name> from another branch in the local repository, you can point branch.<name>.merge to the desired branch, and use the relative path setting . (a period) for branch.<name>.remote.

branch.<name>.mergeoptions
    Sets default options for merging into branch <name>. The syntax and supported options are the same as those of git-merge(1), but option values containing whitespace characters are currently not supported.

branch.<name>.rebase
    When true, rebase the branch <name> on top of the fetched branch, instead of merging the default branch from the default remote when "git pull" is run. See "pull.rebase" for doing this in a non branch-specific manner.

        When preserve, also pass `--preserve-merges` along to 'git rebase'
        so that locally committed merge commits will not be flattened
        by running 'git pull'.

    NOTE: this is a possibly dangerous operation; do not use it unless you understand the implications (see git-rebase(1) for details).

branch.<name>.description
    Branch description, can be edited with git branch --edit-description. Branch description is automatically added in the format-patch cover letter or request-pull summary.

browser.<tool>.cmd
    Specify the command to invoke the specified browser. The specified command is evaluated in shell with the URLs passed as arguments. (See git-web--browse(1).)

browser.<tool>.path
    Override the path for the given tool that may be used to browse HTML help (see -w option in git-help(1)) or a working repository in gitweb (see git-instaweb(1)).

clean.requireForce
    A boolean to make git-clean do nothing unless given -f, -i or -n. Defaults to true.

color.branch
    A boolean to enable/disable color in the output of git-branch(1). May be set to always, false (or never) or auto (or true), in which case colors are used only when the output is to a terminal. Defaults to false.

color.branch.<slot>
    Use customized color for branch coloration. <slot> is one of current (the current branch), local (a local branch), remote (a remote-tracking branch in refs/remotes/), upstream (upstream tracking branch), plain (other refs).

    The value for these configuration variables is a list of colors (at most two) and attributes (at most one), separated by spaces. The colors accepted are normal, black, red, green, yellow, blue, magenta, cyan and white; the attributes are bold, dim, ul, blink and reverse. The first color given is the foreground; the second is the background. The position of the attribute, if any, doesn’t matter.

color.diff
    Whether to use ANSI escape sequences to add color to patches. If this is set to always, git-diff(1), git-log(1), and git-show(1) will use color for all patches. If it is set to true or auto, those commands will only use color when output is to the terminal. Defaults to false.

    This does not affect git-format-patch(1) or the git-diff-* plumbing commands. Can be overridden on the command line with the --color[=<when>] option.

color.diff.<slot>
    Use customized color for diff colorization. <slot> specifies which part of the patch to use the specified color, and is one of plain (context text), meta (metainformation), frag (hunk header), func (function in hunk header), old (removed lines), new (added lines), commit (commit headers), or whitespace (highlighting whitespace errors). The values of these variables may be specified as in color.branch.<slot>.

color.decorate.<slot>
    Use customized color for git log --decorate output. <slot> is one of branch, remoteBranch, tag, stash or HEAD for local branches, remote-tracking branches, tags, stash and HEAD, respectively.

color.grep
    When set to always, always highlight matches. When false (or never), never. When set to true or auto, use color only when the output is written to the terminal. Defaults to false.

color.grep.<slot>
    Use customized color for grep colorization. <slot> specifies which part of the line to use the specified color, and is one of

    context
        non-matching text in context lines (when using -A, -B, or -C)

    filename
        filename prefix (when not using -h)

    function
        function name lines (when using -p)

    linenumber
        line number prefix (when using -n)

    match
        matching text

    selected
        non-matching text in selected lines

    separator
        separators between fields on a line (:, -, and =) and between hunks (--)

    The values of these variables may be specified as in color.branch.<slot>.

color.interactive
    When set to always, always use colors for interactive prompts and displays (such as those used by "git-add --interactive" and "git-clean --interactive"). When false (or never), never. When set to true or auto, use colors only when the output is to the terminal. Defaults to false.

color.interactive.<slot>
    Use customized color for git add --interactive and git clean --interactive output. <slot> may be prompt, header, help or error, for four distinct types of normal output from interactive commands. The values of these variables may be specified as in color.branch.<slot>.

color.pager
    A boolean to enable/disable colored output when the pager is in use (default is true).

color.showbranch
    A boolean to enable/disable color in the output of git-show-branch(1). May be set to always, false (or never) or auto (or true), in which case colors are used only when the output is to a terminal. Defaults to false.

color.status
    A boolean to enable/disable color in the output of git-status(1). May be set to always, false (or never) or auto (or true), in which case colors are used only when the output is to a terminal. Defaults to false.

color.status.<slot>
    Use customized color for status colorization. <slot> is one of header (the header text of the status message), added or updated (files which are added but not committed), changed (files which are changed but not added in the index), untracked (files which are not tracked by Git), branch (the current branch), or nobranch (the color the no branch warning is shown in, defaulting to red). The values of these variables may be specified as in color.branch.<slot>.

color.ui
    This variable determines the default value for variables such as color.diff and color.grep that control the use of color per command family. Its scope will expand as more commands learn configuration to set a default for the --color option. Set it to false or never if you prefer Git commands not to use color unless enabled explicitly with some other configuration or the --color option. Set it to always if you want all output not intended for machine consumption to use color, to true or auto (this is the default since Git 1.8.4) if you want such output to use color when written to the terminal.

column.ui
    Specify whether supported commands should output in columns. This variable consists of a list of tokens separated by spaces or commas:

    These options control when the feature should be enabled (defaults to never):

    always
        always show in columns

    never
        never show in columns

    auto
        show in columns if the output is to the terminal

    These options control layout (defaults to column). Setting any of these implies always if none of always, never, or auto are specified.

    column
        fill columns before rows

    row
        fill rows before columns

    plain
        show in one column

    Finally, these options can be combined with a layout option (defaults to nodense):

    dense
        make unequal size columns to utilize more space

    nodense
        make equal size columns

column.branch
    Specify whether to output branch listing in git branch in columns. See column.ui for details.

column.clean
    Specify the layout when list items in git clean -i, which always shows files and directories in columns. See column.ui for details.

column.status
    Specify whether to output untracked files in git status in columns. See column.ui for details.

column.tag
    Specify whether to output tag listing in git tag in columns. See column.ui for details.

commit.cleanup
    This setting overrides the default of the --cleanup option in git commit. See git-commit(1) for details. Changing the default can be useful when you always want to keep lines that begin with comment character # in your log message, in which case you would do git config commit.cleanup whitespace (note that you will have to remove the help lines that begin with # in the commit log template yourself, if you do this).

commit.status
    A boolean to enable/disable inclusion of status information in the commit message template when using an editor to prepare the commit message. Defaults to true.

commit.template
    Specify a file to use as the template for new commit messages. "~/" is expanded to the value of $HOME and "~user/" to the specified user’s home directory.

credential.helper
    Specify an external helper to be called when a username or password credential is needed; the helper may consult external storage to avoid prompting the user for the credentials. See gitcredentials(7) for details.

credential.useHttpPath
    When acquiring credentials, consider the "path" component of an http or https URL to be important. Defaults to false. See gitcredentials(7) for more information.

credential.username
    If no username is set for a network authentication, use this username by default. See credential.<context>.* below, and gitcredentials(7).

credential.<url>.*
    Any of the credential.* options above can be applied selectively to some credentials. For example "credential.https://example.com.username" would set the default username only for https connections to example.com. See gitcredentials(7) for details on how URLs are matched.

diff.autorefreshindex
    When using git diff to compare with work tree files, do not consider stat-only change as changed. Instead, silently run git update-index --refresh to update the cached stat information for paths whose contents in the work tree match the contents in the index. This option defaults to true. Note that this affects only git diff Porcelain, and not lower level diff commands such as git diff-files.

diff.dirstat
    A comma separated list of --dirstat parameters specifying the default behavior of the --dirstat option to git-diff(1)` and friends. The defaults can be overridden on the command line (using --dirstat=<param1,param2,...>). The fallback defaults (when not changed by diff.dirstat) are changes,noncumulative,3. The following parameters are available:

    changes
        Compute the dirstat numbers by counting the lines that have been removed from the source, or added to the destination. This ignores the amount of pure code movements within a file. In other words, rearranging lines in a file is not counted as much as other changes. This is the default behavior when no parameter is given.

    lines
        Compute the dirstat numbers by doing the regular line-based diff analysis, and summing the removed/added line counts. (For binary files, count 64-byte chunks instead, since binary files have no natural concept of lines). This is a more expensive --dirstat behavior than the changes behavior, but it does count rearranged lines within a file as much as other changes. The resulting output is consistent with what you get from the other --*stat options.

    files
        Compute the dirstat numbers by counting the number of files changed. Each changed file counts equally in the dirstat analysis. This is the computationally cheapest --dirstat behavior, since it does not have to look at the file contents at all.

    cumulative
        Count changes in a child directory for the parent directory as well. Note that when using cumulative, the sum of the percentages reported may exceed 100%. The default (non-cumulative) behavior can be specified with the noncumulative parameter.

    <limit>
        An integer parameter specifies a cut-off percent (3% by default). Directories contributing less than this percentage of the changes are not shown in the output.

    Example: The following will count changed files, while ignoring directories with less than 10% of the total amount of changed files, and accumulating child directory counts in the parent directories: files,10,cumulative.

diff.statGraphWidth
    Limit the width of the graph part in --stat output. If set, applies to all commands generating --stat output except format-patch.

diff.context
    Generate diffs with <n> lines of context instead of the default of 3. This value is overridden by the -U option.

diff.external
    If this config variable is set, diff generation is not performed using the internal diff machinery, but using the given command. Can be overridden with the ‘GIT_EXTERNAL_DIFF’ environment variable. The command is called with parameters as described under "git Diffs" in git(1). Note: if you want to use an external diff program only on a subset of your files, you might want to use gitattributes(5) instead.

diff.ignoreSubmodules
    Sets the default value of --ignore-submodules. Note that this affects only git diff Porcelain, and not lower level diff commands such as git diff-files. git checkout also honors this setting when reporting uncommitted changes. Setting it to all disables the submodule summary normally shown by git commit and git status when status.submodulesummary is set unless it is overridden by using the --ignore-submodules command line option. The git submodule commands are not affected by this setting.

diff.mnemonicprefix
    If set, git diff uses a prefix pair that is different from the standard "a/" and "b/" depending on what is being compared. When this configuration is in effect, reverse diff output also swaps the order of the prefixes:

    git diff
        compares the (i)ndex and the (w)ork tree;

    git diff HEAD
        compares a (c)ommit and the (w)ork tree;

    git diff --cached
        compares a (c)ommit and the (i)ndex;

    git diff HEAD:file1 file2
        compares an (o)bject and a (w)ork tree entity;

    git diff --no-index a b
        compares two non-git things (1) and (2).

diff.noprefix
    If set, git diff does not show any source or destination prefix.

diff.orderfile
    File indicating how to order files within a diff, using one shell glob pattern per line. Can be overridden by the -O option to git-diff(1).

diff.renameLimit
    The number of files to consider when performing the copy/rename detection; equivalent to the git diff option -l.

diff.renames
    Tells Git to detect renames. If set to any boolean value, it will enable basic rename detection. If set to "copies" or "copy", it will detect copies, as well.

diff.suppressBlankEmpty
    A boolean to inhibit the standard behavior of printing a space before each empty output line. Defaults to false.

diff.submodule
    Specify the format in which differences in submodules are shown. The "log" format lists the commits in the range like git-submodule(1) summary does. The "short" format format just shows the names of the commits at the beginning and end of the range. Defaults to short.

diff.wordRegex
    A POSIX Extended Regular Expression used to determine what is a "word" when performing word-by-word difference calculations. Character sequences that match the regular expression are "words", all other characters are ignorable whitespace.

diff.<driver>.command
    The custom diff driver command. See gitattributes(5) for details.

diff.<driver>.xfuncname
    The regular expression that the diff driver should use to recognize the hunk header. A built-in pattern may also be used. See gitattributes(5) for details.

diff.<driver>.binary
    Set this option to true to make the diff driver treat files as binary. See gitattributes(5) for details.

diff.<driver>.textconv
    The command that the diff driver should call to generate the text-converted version of a file. The result of the conversion is used to generate a human-readable diff. See gitattributes(5) for details.

diff.<driver>.wordregex
    The regular expression that the diff driver should use to split words in a line. See gitattributes(5) for details.

diff.<driver>.cachetextconv
    Set this option to true to make the diff driver cache the text conversion outputs. See gitattributes(5) for details.

diff.tool
    Controls which diff tool is used by git-difftool(1). This variable overrides the value configured in merge.tool. The list below shows the valid built-in values. Any other value is treated as a custom diff tool and requires that a corresponding difftool.<tool>.cmd variable is defined.

diff.algorithm
    Choose a diff algorithm. The variants are as follows:

    default, myers
        The basic greedy diff algorithm. Currently, this is the default.

    minimal
        Spend extra time to make sure the smallest possible diff is produced.

    patience
        Use "patience diff" algorithm when generating patches.

    histogram
        This algorithm extends the patience algorithm to "support low-occurrence common elements".

difftool.<tool>.path
    Override the path for the given tool. This is useful in case your tool is not in the PATH.

difftool.<tool>.cmd
    Specify the command to invoke the specified diff tool. The specified command is evaluated in shell with the following variables available: LOCAL is set to the name of the temporary file containing the contents of the diff pre-image and REMOTE is set to the name of the temporary file containing the contents of the diff post-image.

difftool.prompt
    Prompt before each invocation of the diff tool.

fetch.recurseSubmodules
    This option can be either set to a boolean value or to on-demand. Setting it to a boolean changes the behavior of fetch and pull to unconditionally recurse into submodules when set to true or to not recurse at all when set to false. When set to on-demand (the default value), fetch and pull will only recurse into a populated submodule when its superproject retrieves a commit that updates the submodule’s reference.

fetch.fsckObjects
    If it is set to true, git-fetch-pack will check all fetched objects. It will abort in the case of a malformed object or a broken link. The result of an abort are only dangling objects. Defaults to false. If not set, the value of transfer.fsckObjects is used instead.

fetch.unpackLimit
    If the number of objects fetched over the Git native transfer is below this limit, then the objects will be unpacked into loose object files. However if the number of received objects equals or exceeds this limit then the received pack will be stored as a pack, after adding any missing delta bases. Storing the pack from a push can make the push operation complete faster, especially on slow filesystems. If not set, the value of transfer.unpackLimit is used instead.

fetch.prune
    If true, fetch will automatically behave as if the --prune option was given on the command line. See also remote.<name>.prune.

format.attach
    Enable multipart/mixed attachments as the default for format-patch. The value can also be a double quoted string which will enable attachments as the default and set the value as the boundary. See the --attach option in git-format-patch(1).

format.numbered
    A boolean which can enable or disable sequence numbers in patch subjects. It defaults to "auto" which enables it only if there is more than one patch. It can be enabled or disabled for all messages by setting it to "true" or "false". See --numbered option in git-format-patch(1).

format.headers
    Additional email headers to include in a patch to be submitted by mail. See git-format-patch(1).

format.to, format.cc
    Additional recipients to include in a patch to be submitted by mail. See the --to and --cc options in git-format-patch(1).

format.subjectprefix
    The default for format-patch is to output files with the [PATCH] subject prefix. Use this variable to change that prefix.

format.signature
    The default for format-patch is to output a signature containing the Git version number. Use this variable to change that default. Set this variable to the empty string ("") to suppress signature generation.

format.suffix
    The default for format-patch is to output files with the suffix .patch. Use this variable to change that suffix (make sure to include the dot if you want it).

format.pretty
    The default pretty format for log/show/whatchanged command, See git-log(1), git-show(1), git-whatchanged(1).

format.thread
    The default threading style for git format-patch. Can be a boolean value, or shallow or deep. shallow threading makes every mail a reply to the head of the series, where the head is chosen from the cover letter, the --in-reply-to, and the first patch mail, in this order. deep threading makes every mail a reply to the previous one. A true boolean value is the same as shallow, and a false value disables threading.

format.signoff
    A boolean value which lets you enable the -s/--signoff option of format-patch by default. Note: Adding the Signed-off-by: line to a patch should be a conscious act and means that you certify you have the rights to submit this work under the same open source license. Please see the SubmittingPatches document for further discussion.

format.coverLetter
    A boolean that controls whether to generate a cover-letter when format-patch is invoked, but in addition can be set to "auto", to generate a cover-letter only when there’s more than one patch.

filter.<driver>.clean
    The command which is used to convert the content of a worktree file to a blob upon checkin. See gitattributes(5) for details.

filter.<driver>.smudge
    The command which is used to convert the content of a blob object to a worktree file upon checkout. See gitattributes(5) for details.

gc.aggressiveWindow
    The window size parameter used in the delta compression algorithm used by git gc --aggressive. This defaults to 250.

gc.auto
    When there are approximately more than this many loose objects in the repository, git gc --auto will pack them. Some Porcelain commands use this command to perform a light-weight garbage collection from time to time. The default value is 6700. Setting this to 0 disables it.

gc.autopacklimit
    When there are more than this many packs that are not marked with *.keep file in the repository, git gc --auto consolidates them into one larger pack. The default value is 50. Setting this to 0 disables it.

gc.packrefs
    Running git pack-refs in a repository renders it unclonable by Git versions prior to 1.5.1.2 over dumb transports such as HTTP. This variable determines whether git gc runs git pack-refs. This can be set to notbare to enable it within all non-bare repos or it can be set to a boolean value. The default is true.

gc.pruneexpire
    When git gc is run, it will call prune --expire 2.weeks.ago. Override the grace period with this config variable. The value "now" may be used to disable this grace period and always prune unreachable objects immediately.

gc.reflogexpire, gc.<pattern>.reflogexpire
    git reflog expire removes reflog entries older than this time; defaults to 90 days. With "<pattern>" (e.g. "refs/stash") in the middle the setting applies only to the refs that match the <pattern>.

gc.reflogexpireunreachable, gc.<ref>.reflogexpireunreachable
    git reflog expire removes reflog entries older than this time and are not reachable from the current tip; defaults to 30 days. With "<pattern>" (e.g. "refs/stash") in the middle, the setting applies only to the refs that match the <pattern>.

gc.rerereresolved
    Records of conflicted merge you resolved earlier are kept for this many days when git rerere gc is run. The default is 60 days. See git-rerere(1).

gc.rerereunresolved
    Records of conflicted merge you have not resolved are kept for this many days when git rerere gc is run. The default is 15 days. See git-rerere(1).

gitcvs.commitmsgannotation
    Append this string to each commit message. Set to empty string to disable this feature. Defaults to "via git-CVS emulator".

gitcvs.enabled
    Whether the CVS server interface is enabled for this repository. See git-cvsserver(1).

gitcvs.logfile
    Path to a log file where the CVS server interface well... logs various stuff. See git-cvsserver(1).

gitcvs.usecrlfattr
    If true, the server will look up the end-of-line conversion attributes for files to determine the -k modes to use. If the attributes force Git to treat a file as text, the -k mode will be left blank so CVS clients will treat it as text. If they suppress text conversion, the file will be set with -kb mode, which suppresses any newline munging the client might otherwise do. If the attributes do not allow the file type to be determined, then gitcvs.allbinary is used. See gitattributes(5).

gitcvs.allbinary
    This is used if gitcvs.usecrlfattr does not resolve the correct -kb mode to use. If true, all unresolved files are sent to the client in mode -kb. This causes the client to treat them as binary files, which suppresses any newline munging it otherwise might do. Alternatively, if it is set to "guess", then the contents of the file are examined to decide if it is binary, similar to core.autocrlf.

gitcvs.dbname
    Database used by git-cvsserver to cache revision information derived from the Git repository. The exact meaning depends on the used database driver, for SQLite (which is the default driver) this is a filename. Supports variable substitution (see git-cvsserver(1) for details). May not contain semicolons (;). Default: %Ggitcvs.%m.sqlite

gitcvs.dbdriver
    Used Perl DBI driver. You can specify any available driver for this here, but it might not work. git-cvsserver is tested with DBD::SQLite, reported to work with DBD::Pg, and reported not to work with DBD::mysql. Experimental feature. May not contain double colons (:). Default: SQLite. See git-cvsserver(1).

gitcvs.dbuser, gitcvs.dbpass
    Database user and password. Only useful if setting gitcvs.dbdriver, since SQLite has no concept of database users and/or passwords. gitcvs.dbuser supports variable substitution (see git-cvsserver(1) for details).

gitcvs.dbTableNamePrefix
    Database table name prefix. Prepended to the names of any database tables used, allowing a single database to be used for several repositories. Supports variable substitution (see git-cvsserver(1) for details). Any non-alphabetic characters will be replaced with underscores.

All gitcvs variables except for gitcvs.usecrlfattr and gitcvs.allbinary can also be specified as gitcvs.<access_method>.<varname> (where access_method is one of "ext" and "pserver") to make them apply only for the given access method.

gitweb.category, gitweb.description, gitweb.owner, gitweb.url
    See gitweb(1) for description.

gitweb.avatar, gitweb.blame, gitweb.grep, gitweb.highlight, gitweb.patches, gitweb.pickaxe, gitweb.remote_heads, gitweb.showsizes, gitweb.snapshot
    See gitweb.conf(5) for description.

grep.lineNumber
    If set to true, enable -n option by default.

grep.patternType
    Set the default matching behavior. Using a value of basic, extended, fixed, or perl will enable the --basic-regexp, --extended-regexp, --fixed-strings, or --perl-regexp option accordingly, while the value default will return to the default matching behavior.

grep.extendedRegexp
    If set to true, enable --extended-regexp option by default. This option is ignored when the grep.patternType option is set to a value other than default.

gpg.program
    Use this custom program instead of "gpg" found on $PATH when making or verifying a PGP signature. The program must support the same command line interface as GPG, namely, to verify a detached signature, "gpg --verify $file - <$signature" is run, and the program is expected to signal a good signature by exiting with code 0, and to generate an ascii-armored detached signature, the standard input of "gpg -bsau $key" is fed with the contents to be signed, and the program is expected to send the result to its standard output.

gui.commitmsgwidth
    Defines how wide the commit message window is in the git-gui(1). "75" is the default.

gui.diffcontext
    Specifies how many context lines should be used in calls to diff made by the git-gui(1). The default is "5".

gui.encoding
    Specifies the default encoding to use for displaying of file contents in git-gui(1) and gitk(1). It can be overridden by setting the encoding attribute for relevant files (see gitattributes(5)). If this option is not set, the tools default to the locale encoding.

gui.matchtrackingbranch
    Determines if new branches created with git-gui(1) should default to tracking remote branches with matching names or not. Default: "false".

gui.newbranchtemplate
    Is used as suggested name when creating new branches using the git-gui(1).

gui.pruneduringfetch
    "true" if git-gui(1) should prune remote-tracking branches when performing a fetch. The default value is "false".

gui.trustmtime
    Determines if git-gui(1) should trust the file modification timestamp or not. By default the timestamps are not trusted.

gui.spellingdictionary
    Specifies the dictionary used for spell checking commit messages in the git-gui(1). When set to "none" spell checking is turned off.

gui.fastcopyblame
    If true, git gui blame uses -C instead of -C -C for original location detection. It makes blame significantly faster on huge repositories at the expense of less thorough copy detection.

gui.copyblamethreshold
    Specifies the threshold to use in git gui blame original location detection, measured in alphanumeric characters. See the git-blame(1) manual for more information on copy detection.

gui.blamehistoryctx
    Specifies the radius of history context in days to show in gitk(1) for the selected commit, when the Show History Context menu item is invoked from git gui blame. If this variable is set to zero, the whole history is shown.

guitool.<name>.cmd
    Specifies the shell command line to execute when the corresponding item of the git-gui(1) Tools menu is invoked. This option is mandatory for every tool. The command is executed from the root of the working directory, and in the environment it receives the name of the tool as GIT_GUITOOL, the name of the currently selected file as FILENAME, and the name of the current branch as CUR_BRANCH (if the head is detached, CUR_BRANCH is empty).

guitool.<name>.needsfile
    Run the tool only if a diff is selected in the GUI. It guarantees that FILENAME is not empty.

guitool.<name>.noconsole
    Run the command silently, without creating a window to display its output.

guitool.<name>.norescan
    Don’t rescan the working directory for changes after the tool finishes execution.

guitool.<name>.confirm
    Show a confirmation dialog before actually running the tool.

guitool.<name>.argprompt
    Request a string argument from the user, and pass it to the tool through the ARGS environment variable. Since requesting an argument implies confirmation, the confirm option has no effect if this is enabled. If the option is set to true, yes, or 1, the dialog uses a built-in generic prompt; otherwise the exact value of the variable is used.

guitool.<name>.revprompt
    Request a single valid revision from the user, and set the REVISION environment variable. In other aspects this option is similar to argprompt, and can be used together with it.

guitool.<name>.revunmerged
    Show only unmerged branches in the revprompt subdialog. This is useful for tools similar to merge or rebase, but not for things like checkout or reset.

guitool.<name>.title
    Specifies the title to use for the prompt dialog. The default is the tool name.

guitool.<name>.prompt
    Specifies the general prompt string to display at the top of the dialog, before subsections for argprompt and revprompt. The default value includes the actual command.

help.browser
    Specify the browser that will be used to display help in the web format. See git-help(1).

help.format
    Override the default help format used by git-help(1). Values man, info, web and html are supported. man is the default. web and html are the same.

help.autocorrect
    Automatically correct and execute mistyped commands after waiting for the given number of deciseconds (0.1 sec). If more than one command can be deduced from the entered text, nothing will be executed. If the value of this option is negative, the corrected command will be executed immediately. If the value is 0 - the command will be just shown but not executed. This is the default.

help.htmlpath
    Specify the path where the HTML documentation resides. File system paths and URLs are supported. HTML pages will be prefixed with this path when help is displayed in the web format. This defaults to the documentation path of your Git installation.

http.proxy
    Override the HTTP proxy, normally configured using the http_proxy, https_proxy, and all_proxy environment variables (see curl(1)). This can be overridden on a per-remote basis; see remote.<name>.proxy

http.cookiefile
    File containing previously stored cookie lines which should be used in the Git http session, if they match the server. The file format of the file to read cookies from should be plain HTTP headers or the Netscape/Mozilla cookie file format (see curl(1)). NOTE that the file specified with http.cookiefile is only used as input unless http.saveCookies is set.

http.savecookies
    If set, store cookies received during requests to the file specified by http.cookiefile. Has no effect if http.cookiefile is unset.

http.sslVerify
    Whether to verify the SSL certificate when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_NO_VERIFY environment variable.

http.sslCert
    File containing the SSL certificate when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CERT environment variable.

http.sslKey
    File containing the SSL private key when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_KEY environment variable.

http.sslCertPasswordProtected
    Enable Git’s password prompt for the SSL certificate. Otherwise OpenSSL will prompt the user, possibly many times, if the certificate or private key is encrypted. Can be overridden by the GIT_SSL_CERT_PASSWORD_PROTECTED environment variable.

http.sslCAInfo
    File containing the certificates to verify the peer with when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CAINFO environment variable.

http.sslCAPath
    Path containing files with the CA certificates to verify the peer with when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CAPATH environment variable.

http.sslTry
    Attempt to use AUTH SSL/TLS and encrypted data transfers when connecting via regular FTP protocol. This might be needed if the FTP server requires it for security reasons or you wish to connect securely whenever remote FTP server supports it. Default is false since it might trigger certificate verification errors on misconfigured servers.

http.maxRequests
    How many HTTP requests to launch in parallel. Can be overridden by the GIT_HTTP_MAX_REQUESTS environment variable. Default is 5.

http.minSessions
    The number of curl sessions (counted across slots) to be kept across requests. They will not be ended with curl_easy_cleanup() until http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this value will be capped at 1. Defaults to 1.

http.postBuffer
    Maximum size in bytes of the buffer used by smart HTTP transports when POSTing data to the remote system. For requests larger than this buffer size, HTTP/1.1 and Transfer-Encoding: chunked is used to avoid creating a massive pack file locally. Default is 1 MiB, which is sufficient for most requests.

http.lowSpeedLimit, http.lowSpeedTime
    If the HTTP transfer speed is less than http.lowSpeedLimit for longer than http.lowSpeedTime seconds, the transfer is aborted. Can be overridden by the GIT_HTTP_LOW_SPEED_LIMIT and GIT_HTTP_LOW_SPEED_TIME environment variables.

http.noEPSV
    A boolean which disables using of EPSV ftp command by curl. This can helpful with some "poor" ftp servers which don’t support EPSV mode. Can be overridden by the GIT_CURL_FTP_NO_EPSV environment variable. Default is false (curl will use EPSV).

http.useragent
    The HTTP USER_AGENT string presented to an HTTP server. The default value represents the version of the client Git such as git/1.7.1. This option allows you to override this value to a more common value such as Mozilla/4.0. This may be necessary, for instance, if connecting through a firewall that restricts HTTP connections to a set of common USER_AGENT strings (but not including those like git/1.7.1). Can be overridden by the GIT_HTTP_USER_AGENT environment variable.

http.<url>.*
    Any of the http.* options above can be applied selectively to some urls. For a config key to match a URL, each element of the config key is compared to that of the URL, in the following order:

        1. Scheme (e.g., https in https://example.com/). This field must match exactly between the config key and the URL.

        2. Host/domain name (e.g., example.com in https://example.com/). This field must match exactly between the config key and the URL.

        3. Port number (e.g., 8080 in http://example.com:8080/). This field must match exactly between the config key and the URL. Omitted port numbers are automatically converted to the correct default for the scheme before matching.

        4. Path (e.g., repo.git in https://example.com/repo.git). The path field of the config key must match the path field of the URL either exactly or as a prefix of slash-delimited path elements. This means a config key with path foo/ matches URL path foo/bar. A prefix can only match on a slash (/) boundary. Longer matches take precedence (so a config key with path foo/bar is a better match to URL path foo/bar than a config key with just path foo/).

        5. User name (e.g., user in https://user@example.com/repo.git). If the config key has a user name it must match the user name in the URL exactly. If the config key does not have a user name, that config key will match a URL with any user name (including none), but at a lower precedence than a config key with a user name.

    The list above is ordered by decreasing precedence; a URL that matches a config key’s path is preferred to one that matches its user name. For example, if the URL is https://user@example.com/foo/bar a config key match of https://example.com/foo will be preferred over a config key match of https://user@example.com.

    All URLs are normalized before attempting any matching (the password part, if embedded in the URL, is always ignored for matching purposes) so that equivalent urls that are simply spelled differently will match properly. Environment variable settings always override any matches. The urls that are matched against are those given directly to Git commands. This means any URLs visited as a result of a redirection do not participate in matching.

i18n.commitEncoding
    Character encoding the commit messages are stored in; Git itself does not care per se, but this information is necessary e.g. when importing commits from emails or in the gitk graphical history browser (and possibly at other places in the future or in other porcelains). See e.g. git-mailinfo(1). Defaults to utf-8.

i18n.logOutputEncoding
    Character encoding the commit messages are converted to when running git log and friends.

imap
    The configuration variables in the imap section are described in git-imap-send(1).

init.templatedir
    Specify the directory from which templates will be copied. (See the "TEMPLATE DIRECTORY" section of git-init(1).)

instaweb.browser
    Specify the program that will be used to browse your working repository in gitweb. See git-instaweb(1).

instaweb.httpd
    The HTTP daemon command-line to start gitweb on your working repository. See git-instaweb(1).

instaweb.local
    If true the web server started by git-instaweb(1) will be bound to the local IP (127.0.0.1).

instaweb.modulepath
    The default module path for git-instaweb(1) to use instead of /usr/lib/apache2/modules. Only used if httpd is Apache.

instaweb.port
    The port number to bind the gitweb httpd to. See git-instaweb(1).

interactive.singlekey
    In interactive commands, allow the user to provide one-letter input with a single key (i.e., without hitting enter). Currently this is used by the --patch mode of git-add(1), git-checkout(1), git-commit(1), git-reset(1), and git-stash(1). Note that this setting is silently ignored if portable keystroke input is not available.

log.abbrevCommit
    If true, makes git-log(1), git-show(1), and git-whatchanged(1) assume --abbrev-commit. You may override this option with --no-abbrev-commit.

log.date
    Set the default date-time mode for the log command. Setting a value for log.date is similar to using git log's --date option. Possible values are relative, local, default, iso, rfc, and short; see git-log(1) for details.

log.decorate
    Print out the ref names of any commits that are shown by the log command. If short is specified, the ref name prefixes refs/heads/, refs/tags/ and refs/remotes/ will not be printed. If full is specified, the full ref name (including prefix) will be printed. This is the same as the log commands --decorate option.

log.showroot
    If true, the initial commit will be shown as a big creation event. This is equivalent to a diff against an empty tree. Tools like git-log(1) or git-whatchanged(1), which normally hide the root commit will now show it. True by default.

log.mailmap
    If true, makes git-log(1), git-show(1), and git-whatchanged(1) assume --use-mailmap.

mailmap.file
    The location of an augmenting mailmap file. The default mailmap, located in the root of the repository, is loaded first, then the mailmap file pointed to by this variable. The location of the mailmap file may be in a repository subdirectory, or somewhere outside of the repository itself. See git-shortlog(1) and git-blame(1).

mailmap.blob
    Like mailmap.file, but consider the value as a reference to a blob in the repository. If both mailmap.file and mailmap.blob are given, both are parsed, with entries from mailmap.file taking precedence. In a bare repository, this defaults to HEAD:.mailmap. In a non-bare repository, it defaults to empty.

man.viewer
    Specify the programs that may be used to display help in the man format. See git-help(1).

man.<tool>.cmd
    Specify the command to invoke the specified man viewer. The specified command is evaluated in shell with the man page passed as argument. (See git-help(1).)

man.<tool>.path
    Override the path for the given tool that may be used to display help in the man format. See git-help(1).

merge.conflictstyle
    Specify the style in which conflicted hunks are written out to working tree files upon merge. The default is "merge", which shows a <<<<<<< conflict marker, changes made by one side, a ======= marker, changes made by the other side, and then a >>>>>>> marker. An alternate style, "diff3", adds a ||||||| marker and the original text before the ======= marker.

merge.defaultToUpstream
    If merge is called without any commit argument, merge the upstream branches configured for the current branch by using their last observed values stored in their remote-tracking branches. The values of the branch.<current branch>.merge that name the branches at the remote named by branch.<current branch>.remote are consulted, and then they are mapped via remote.<remote>.fetch to their corresponding remote-tracking branches, and the tips of these tracking branches are merged.

merge.ff
    By default, Git does not create an extra merge commit when merging a commit that is a descendant of the current commit. Instead, the tip of the current branch is fast-forwarded. When set to false, this variable tells Git to create an extra merge commit in such a case (equivalent to giving the --no-ff option from the command line). When set to only, only such fast-forward merges are allowed (equivalent to giving the --ff-only option from the command line).

merge.log
    In addition to branch names, populate the log message with at most the specified number of one-line descriptions from the actual commits that are being merged. Defaults to false, and true is a synonym for 20.

merge.renameLimit
    The number of files to consider when performing rename detection during a merge; if not specified, defaults to the value of diff.renameLimit.

merge.renormalize
    Tell Git that canonical representation of files in the repository has changed over time (e.g. earlier commits record text files with CRLF line endings, but recent ones use LF line endings). In such a repository, Git can convert the data recorded in commits to a canonical form before performing a merge to reduce unnecessary conflicts. For more information, see section "Merging branches with differing checkin/checkout attributes" in gitattributes(5).

merge.stat
    Whether to print the diffstat between ORIG_HEAD and the merge result at the end of the merge. True by default.

merge.tool
    Controls which merge tool is used by git-mergetool(1). The list below shows the valid built-in values. Any other value is treated as a custom merge tool and requires that a corresponding mergetool.<tool>.cmd variable is defined.

        • araxis

        • bc3

        • codecompare

        • deltawalker

        • vimdiff

        • vimdiff2

        • xxdiff

merge.verbosity
    Controls the amount of output shown by the recursive merge strategy. Level 0 outputs nothing except a final error message if conflicts were detected. Level 1 outputs only conflicts, 2 outputs conflicts and file changes. Level 5 and above outputs debugging information. The default is level 2. Can be overridden by the GIT_MERGE_VERBOSITY environment variable.

merge.<driver>.name
    Defines a human-readable name for a custom low-level merge driver. See gitattributes(5) for details.

merge.<driver>.driver
    Defines the command that implements a custom low-level merge driver. See gitattributes(5) for details.

merge.<driver>.recursive
    Names a low-level merge driver to be used when performing an internal merge between common ancestors. See gitattributes(5) for details.

mergetool.<tool>.path
    Override the path for the given tool. This is useful in case your tool is not in the PATH.

mergetool.<tool>.cmd
    Specify the command to invoke the specified merge tool. The specified command is evaluated in shell with the following variables available: BASE is the name of a temporary file containing the common base of the files to be merged, if available; LOCAL is the name of a temporary file containing the contents of the file on the current branch; REMOTE is the name of a temporary file containing the contents of the file from the branch being merged; MERGED contains the name of the file to which the merge tool should write the results of a successful merge.

mergetool.<tool>.trustExitCode
    For a custom merge command, specify whether the exit code of the merge command can be used to determine whether the merge was successful. If this is not set to true then the merge target file timestamp is checked and the merge assumed to have been successful if the file has been updated, otherwise the user is prompted to indicate the success of the merge.

mergetool.keepBackup
    After performing a merge, the original file with conflict markers can be saved as a file with a .orig extension. If this variable is set to false then this file is not preserved. Defaults to true (i.e. keep the backup files).

mergetool.keepTemporaries
    When invoking a custom merge tool, Git uses a set of temporary files to pass to the tool. If the tool returns an error and this variable is set to true, then these temporary files will be preserved, otherwise they will be removed after the tool has exited. Defaults to false.

mergetool.prompt
    Prompt before each invocation of the merge resolution program.

notes.displayRef
    The (fully qualified) refname from which to show notes when showing commit messages. The value of this variable can be set to a glob, in which case notes from all matching refs will be shown. You may also specify this configuration variable several times. A warning will be issued for refs that do not exist, but a glob that does not match any refs is silently ignored.

    This setting can be overridden with the GIT_NOTES_DISPLAY_REF environment variable, which must be a colon separated list of refs or globs.

    The effective value of "core.notesRef" (possibly overridden by GIT_NOTES_REF) is also implicitly added to the list of refs to be displayed.

notes.rewrite.<command>
    When rewriting commits with <command> (currently amend or rebase) and this variable is set to true, Git automatically copies your notes from the original to the rewritten commit. Defaults to true, but see "notes.rewriteRef" below.

notes.rewriteMode
    When copying notes during a rewrite (see the "notes.rewrite.<command>" option), determines what to do if the target commit already has a note. Must be one of overwrite, concatenate, or ignore. Defaults to concatenate.

    This setting can be overridden with the GIT_NOTES_REWRITE_MODE environment variable.

notes.rewriteRef
    When copying notes during a rewrite, specifies the (fully qualified) ref whose notes should be copied. The ref may be a glob, in which case notes in all matching refs will be copied. You may also specify this configuration several times.

    Does not have a default value; you must configure this variable to enable note rewriting. Set it to refs/notes/commits to enable rewriting for the default commit notes.

    This setting can be overridden with the GIT_NOTES_REWRITE_REF environment variable, which must be a colon separated list of refs or globs.

pack.window
    The size of the window used by git-pack-objects(1) when no window size is given on the command line. Defaults to 10.

pack.depth
    The maximum delta depth used by git-pack-objects(1) when no maximum depth is given on the command line. Defaults to 50.

pack.windowMemory
    The window memory size limit used by git-pack-objects(1) when no limit is given on the command line. The value can be suffixed with "k", "m", or "g". Defaults to 0, meaning no limit.

pack.compression
    An integer -1..9, indicating the compression level for objects in a pack file. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If not set, defaults to core.compression. If that is not set, defaults to -1, the zlib default, which is "a default compromise between speed and compression (currently equivalent to level 6)."

    Note that changing the compression level will not automatically recompress all existing objects. You can force recompression by passing the -F option to git-repack(1).

pack.deltaCacheSize
    The maximum memory in bytes used for caching deltas in git-pack-objects(1) before writing them out to a pack. This cache is used to speed up the writing object phase by not having to recompute the final delta result once the best match for all objects is found. Repacking large repositories on machines which are tight with memory might be badly impacted by this though, especially if this cache pushes the system into swapping. A value of 0 means no limit. The smallest size of 1 byte may be used to virtually disable this cache. Defaults to 256 MiB.

pack.deltaCacheLimit
    The maximum size of a delta, that is cached in git-pack-objects(1). This cache is used to speed up the writing object phase by not having to recompute the final delta result once the best match for all objects is found. Defaults to 1000.

pack.threads
    Specifies the number of threads to spawn when searching for best delta matches. This requires that git-pack-objects(1) be compiled with pthreads otherwise this option is ignored with a warning. This is meant to reduce packing time on multiprocessor machines. The required amount of memory for the delta search window is however multiplied by the number of threads. Specifying 0 will cause Git to auto-detect the number of CPU’s and set the number of threads accordingly.

pack.indexVersion
    Specify the default pack index version. Valid values are 1 for legacy pack index used by Git versions prior to 1.5.2, and 2 for the new pack index with capabilities for packs larger than 4 GB as well as proper protection against the repacking of corrupted packs. Version 2 is the default. Note that version 2 is enforced and this config option ignored whenever the corresponding pack is larger than 2 GB.

    If you have an old Git that does not understand the version 2 *.idx file, cloning or fetching over a non native protocol (e.g. "http" and "rsync") that will copy both *.pack file and corresponding *.idx file from the other side may give you a repository that cannot be accessed with your older version of Git. If the *.pack file is smaller than 2 GB, however, you can use git-index-pack(1) on the *.pack file to regenerate the *.idx file.

pack.packSizeLimit
    The maximum size of a pack. This setting only affects packing to a file when repacking, i.e. the git:// protocol is unaffected. It can be overridden by the --max-pack-size option of git-repack(1). The minimum size allowed is limited to 1 MiB. The default is unlimited. Common unit suffixes of k, m, or g are supported.

pager.<cmd>
    If the value is boolean, turns on or off pagination of the output of a particular Git subcommand when writing to a tty. Otherwise, turns on pagination for the subcommand using the pager specified by the value of pager.<cmd>. If --paginate or --no-pager is specified on the command line, it takes precedence over this option. To disable pagination for all commands, set core.pager or GIT_PAGER to cat.

pretty.<name>
    Alias for a --pretty= format string, as specified in git-log(1). Any aliases defined here can be used just as the built-in pretty formats could. For example, running git config pretty.changelog "format:* %H %s" would cause the invocation git log --pretty=changelog to be equivalent to running git log "--pretty=format:* %H %s". Note that an alias with the same name as a built-in format will be silently ignored.

pull.rebase
    When true, rebase branches on top of the fetched branch, instead of merging the default branch from the default remote when "git pull" is run. See "branch.<name>.rebase" for setting this on a per-branch basis.

        When preserve, also pass `--preserve-merges` along to 'git rebase'
        so that locally committed merge commits will not be flattened
        by running 'git pull'.

    NOTE: this is a possibly dangerous operation; do not use it unless you understand the implications (see git-rebase(1) for details).

pull.octopus
    The default merge strategy to use when pulling multiple branches at once.

pull.twohead
    The default merge strategy to use when pulling a single branch.

push.default
    Defines the action git push should take if no refspec is explicitly given. Different values are well-suited for specific workflows; for instance, in a purely central workflow (i.e. the fetch source is equal to the push destination), upstream is probably what you want. Possible values are:

        • nothing - do not push anything (error out) unless a refspec is explicitly given. This is primarily meant for people who want to avoid mistakes by always being explicit.

        • current - push the current branch to update a branch with the same name on the receiving end. Works in both central and non-central workflows.

        • upstream - push the current branch back to the branch whose changes are usually integrated into the current branch (which is called @{upstream}). This mode only makes sense if you are pushing to the same repository you would normally pull from (i.e. central workflow).

        • simple - in centralized workflow, work like upstream with an added safety to refuse to push if the upstream branch’s name is different from the local one.

        When pushing to a remote that is different from the remote you normally pull from, work as current. This is the safest option and is suited for beginners.

        This mode will become the default in Git 2.0.

        • matching - push all branches having the same name on both ends. This makes the repository you are pushing to remember the set of branches that will be pushed out (e.g. if you always push maint and master there and no other branches, the repository you push to will have these two branches, and your local maint and master will be pushed there).

        To use this mode effectively, you have to make sure all the branches you would push out are ready to be pushed out before running git push, as the whole point of this mode is to allow you to push all of the branches in one go. If you usually finish work on only one branch and push out the result, while other branches are unfinished, this mode is not for you. Also this mode is not suitable for pushing into a shared central repository, as other people may add new branches there, or update the tip of existing branches outside your control.

        This is currently the default, but Git 2.0 will change the default to simple.

rebase.stat
    Whether to show a diffstat of what changed upstream since the last rebase. False by default.

rebase.autosquash
    If set to true enable --autosquash option by default.

rebase.autostash
    When set to true, automatically create a temporary stash before the operation begins, and apply it after the operation ends. This means that you can run rebase on a dirty worktree. However, use with care: the final stash application after a successful rebase might result in non-trivial conflicts. Defaults to false.

receive.autogc
    By default, git-receive-pack will run "git-gc --auto" after receiving data from git-push and updating refs. You can stop it by setting this variable to false.

receive.fsckObjects
    If it is set to true, git-receive-pack will check all received objects. It will abort in the case of a malformed object or a broken link. The result of an abort are only dangling objects. Defaults to false. If not set, the value of transfer.fsckObjects is used instead.

receive.unpackLimit
    If the number of objects received in a push is below this limit then the objects will be unpacked into loose object files. However if the number of received objects equals or exceeds this limit then the received pack will be stored as a pack, after adding any missing delta bases. Storing the pack from a push can make the push operation complete faster, especially on slow filesystems. If not set, the value of transfer.unpackLimit is used instead.

receive.denyDeletes
    If set to true, git-receive-pack will deny a ref update that deletes the ref. Use this to prevent such a ref deletion via a push.

receive.denyDeleteCurrent
    If set to true, git-receive-pack will deny a ref update that deletes the currently checked out branch of a non-bare repository.

receive.denyCurrentBranch
    If set to true or "refuse", git-receive-pack will deny a ref update to the currently checked out branch of a non-bare repository. Such a push is potentially dangerous because it brings the HEAD out of sync with the index and working tree. If set to "warn", print a warning of such a push to stderr, but allow the push to proceed. If set to false or "ignore", allow such pushes with no message. Defaults to "refuse".

receive.denyNonFastForwards
    If set to true, git-receive-pack will deny a ref update which is not a fast-forward. Use this to prevent such an update via a push, even if that push is forced. This configuration variable is set when initializing a shared repository.

receive.hiderefs
    String(s) receive-pack uses to decide which refs to omit from its initial advertisement. Use more than one definitions to specify multiple prefix strings. A ref that are under the hierarchies listed on the value of this variable is excluded, and is hidden when responding to git push, and an attempt to update or delete a hidden ref by git push is rejected.

receive.updateserverinfo
    If set to true, git-receive-pack will run git-update-server-info after receiving data from git-push and updating refs.

receive.shallowupdate
    If set to true, .git/shallow can be updated when new refs require new shallow roots. Otherwise those refs are rejected.

remote.pushdefault
    The remote to push to by default. Overrides branch.<name>.remote for all branches, and is overridden by branch.<name>.pushremote for specific branches.

remote.<name>.url
    The URL of a remote repository. See git-fetch(1) or git-push(1).

remote.<name>.pushurl
    The push URL of a remote repository. See git-push(1).

remote.<name>.proxy
    For remotes that require curl (http, https and ftp), the URL to the proxy to use for that remote. Set to the empty string to disable proxying for that remote.

remote.<name>.fetch
    The default set of "refspec" for git-fetch(1). See git-fetch(1).

remote.<name>.push
    The default set of "refspec" for git-push(1). See git-push(1).

remote.<name>.mirror
    If true, pushing to this remote will automatically behave as if the --mirror option was given on the command line.

remote.<name>.skipDefaultUpdate
    If true, this remote will be skipped by default when updating using git-fetch(1) or the update subcommand of git-remote(1).

remote.<name>.skipFetchAll
    If true, this remote will be skipped by default when updating using git-fetch(1) or the update subcommand of git-remote(1).

remote.<name>.receivepack
    The default program to execute on the remote side when pushing. See option --receive-pack of git-push(1).

remote.<name>.uploadpack
    The default program to execute on the remote side when fetching. See option --upload-pack of git-fetch-pack(1).

remote.<name>.tagopt
    Setting this value to --no-tags disables automatic tag following when fetching from remote <name>. Setting it to --tags will fetch every tag from remote <name>, even if they are not reachable from remote branch heads. Passing these flags directly to git-fetch(1) can override this setting. See options --tags and --no-tags of git-fetch(1).

remote.<name>.vcs
    Setting this to a value <vcs> will cause Git to interact with the remote with the git-remote-<vcs> helper.

remote.<name>.prune
    When set to true, fetching from this remote by default will also remove any remote-tracking references that no longer exist on the remote (as if the --prune option was given on the command line). Overrides fetch.prune settings, if any.

remotes.<group>
    The list of remotes which are fetched by "git remote update <group>". See git-remote(1).

repack.usedeltabaseoffset
    By default, git-repack(1) creates packs that use delta-base offset. If you need to share your repository with Git older than version 1.4.4, either directly or via a dumb protocol such as http, then you need to set this option to "false" and repack. Access from old Git versions over the native protocol are unaffected by this option.

rerere.autoupdate
    When set to true, git-rerere updates the index with the resulting contents after it cleanly resolves conflicts using previously recorded resolution. Defaults to false.

rerere.enabled
    Activate recording of resolved conflicts, so that identical conflict hunks can be resolved automatically, should they be encountered again. By default, git-rerere(1) is enabled if there is an rr-cache directory under the $GIT_DIR, e.g. if "rerere" was previously used in the repository.

sendemail.identity
    A configuration identity. When given, causes values in the sendemail.<identity> subsection to take precedence over values in the sendemail section. The default identity is the value of sendemail.identity.

sendemail.smtpencryption
    See git-send-email(1) for description. Note that this setting is not subject to the identity mechanism.

sendemail.smtpssl
    Deprecated alias for sendemail.smtpencryption = ssl.

sendemail.smtpsslcertpath
    Path to ca-certificates (either a directory or a single file). Set it to an empty string to disable certificate verification.

sendemail.<identity>.*
    Identity-specific versions of the sendemail.* parameters found below, taking precedence over those when the this identity is selected, through command-line or sendemail.identity.

sendemail.aliasesfile, sendemail.aliasfiletype, sendemail.annotate, sendemail.bcc, sendemail.cc, sendemail.cccmd, sendemail.chainreplyto, sendemail.confirm, sendemail.envelopesender, sendemail.from, sendemail.multiedit, sendemail.signedoffbycc, sendemail.smtppass, sendemail.suppresscc, sendemail.suppressfrom, sendemail.to, sendemail.smtpdomain, sendemail.smtpserver, sendemail.smtpserverport, sendemail.smtpserveroption, sendemail.smtpuser, sendemail.thread, sendemail.validate
    See git-send-email(1) for description.

sendemail.signedoffcc
    Deprecated alias for sendemail.signedoffbycc.

showbranch.default
    The default set of branches for git-show-branch(1). See git-show-branch(1).

status.relativePaths
    By default, git-status(1) shows paths relative to the current directory. Setting this variable to false shows paths relative to the repository root (this was the default for Git prior to v1.5.4).

status.short
    Set to true to enable --short by default in git-status(1). The option --no-short takes precedence over this variable.

status.branch
    Set to true to enable --branch by default in git-status(1). The option --no-branch takes precedence over this variable.

status.displayCommentPrefix
    If set to true, git-status(1) will insert a comment prefix before each output line (starting with core.commentChar, i.e. # by default). This was the behavior of git-status(1) in Git 1.8.4 and previous. Defaults to false.

status.showUntrackedFiles
    By default, git-status(1) and git-commit(1) show files which are not currently tracked by Git. Directories which contain only untracked files, are shown with the directory name only. Showing untracked files means that Git needs to lstat() all all the files in the whole repository, which might be slow on some systems. So, this variable controls how the commands displays the untracked files. Possible values are:

        • no - Show no untracked files.

        • normal - Show untracked files and directories.

        • all - Show also individual files in untracked directories.

    If this variable is not specified, it defaults to normal. This variable can be overridden with the -u|--untracked-files option of git-status(1) and git-commit(1).

status.submodulesummary
    Defaults to false. If this is set to a non zero number or true (identical to -1 or an unlimited number), the submodule summary will be enabled and a summary of commits for modified submodules will be shown (see --summary-limit option of git-submodule(1)). Please note that the summary output command will be suppressed for all submodules when diff.ignoreSubmodules is set to all or only for those submodules where submodule.<name>.ignore=all. To also view the summary for ignored submodules you can either use the --ignore-submodules=dirty command line option or the git submodule summary command, which shows a similar output but does not honor these settings.

submodule.<name>.path, submodule.<name>.url, submodule.<name>.update
    The path within this project, URL, and the updating strategy for a submodule. These variables are initially populated by git submodule init; edit them to override the URL and other values found in the .gitmodules file. See git-submodule(1) and gitmodules(5) for details.

submodule.<name>.branch
    The remote branch name for a submodule, used by git submodule update --remote. Set this option to override the value found in the .gitmodules file. See git-submodule(1) and gitmodules(5) for details.

submodule.<name>.fetchRecurseSubmodules
    This option can be used to control recursive fetching of this submodule. It can be overridden by using the --[no-]recurse-submodules command line option to "git fetch" and "git pull". This setting will override that from in the gitmodules(5) file.

submodule.<name>.ignore
    Defines under what circumstances "git status" and the diff family show a submodule as modified. When set to "all", it will never be considered modified, "dirty" will ignore all changes to the submodules work tree and takes only differences between the HEAD of the submodule and the commit recorded in the superproject into account. "untracked" will additionally let submodules with modified tracked files in their work tree show up. Using "none" (the default when this option is not set) also shows submodules that have untracked files in their work tree as changed. This setting overrides any setting made in .gitmodules for this submodule, both settings can be overridden on the command line by using the "--ignore-submodules" option. The git submodule commands are not affected by this setting.

tar.umask
    This variable can be used to restrict the permission bits of tar archive entries. The default is 0002, which turns off the world write bit. The special value "user" indicates that the archiving user’s umask will be used instead. See umask(2) and git-archive(1).

transfer.fsckObjects
    When fetch.fsckObjects or receive.fsckObjects are not set, the value of this variable is used instead. Defaults to false.

transfer.hiderefs
    This variable can be used to set both receive.hiderefs and uploadpack.hiderefs at the same time to the same values. See entries for these other variables.

transfer.unpackLimit
    When fetch.unpackLimit or receive.unpackLimit are not set, the value of this variable is used instead. The default value is 100.

uploadpack.hiderefs
    String(s) upload-pack uses to decide which refs to omit from its initial advertisement. Use more than one definitions to specify multiple prefix strings. A ref that are under the hierarchies listed on the value of this variable is excluded, and is hidden from git ls-remote, git fetch, etc. An attempt to fetch a hidden ref by git fetch will fail. See also uploadpack.allowtipsha1inwant.

uploadpack.allowtipsha1inwant
    When uploadpack.hiderefs is in effect, allow upload-pack to accept a fetch request that asks for an object at the tip of a hidden ref (by default, such a request is rejected). see also uploadpack.hiderefs.

uploadpack.keepalive
    When upload-pack has started pack-objects, there may be a quiet period while pack-objects prepares the pack. Normally it would output progress information, but if --quiet was used for the fetch, pack-objects will output nothing at all until the pack data begins. Some clients and networks may consider the server to be hung and give up. Setting this option instructs upload-pack to send an empty keepalive packet every uploadpack.keepalive seconds. Setting this option to 0 disables keepalive packets entirely. The default is 5 seconds.

url.<base>.insteadOf
    Any URL that starts with this value will be rewritten to start, instead, with <base>. In cases where some site serves a large number of repositories, and serves them with multiple access methods, and some users need to use different access methods, this feature allows people to specify any of the equivalent URLs and have Git automatically rewrite the URL to the best alternative for the particular user, even for a never-before-seen repository on the site. When more than one insteadOf strings match a given URL, the longest match is used.

url.<base>.pushInsteadOf
    Any URL that starts with this value will not be pushed to; instead, it will be rewritten to start with <base>, and the resulting URL will be pushed to. In cases where some site serves a large number of repositories, and serves them with multiple access methods, some of which do not allow push, this feature allows people to specify a pull-only URL and have Git automatically use an appropriate URL to push, even for a never-before-seen repository on the site. When more than one pushInsteadOf strings match a given URL, the longest match is used. If a remote has an explicit pushurl, Git will ignore this setting for that remote.

user.email
    Your email address to be recorded in any newly created commits. Can be overridden by the GIT_AUTHOR_EMAIL, GIT_COMMITTER_EMAIL, and EMAIL environment variables. See git-commit-tree(1).

user.name
    Your full name to be recorded in any newly created commits. Can be overridden by the GIT_AUTHOR_NAME and GIT_COMMITTER_NAME environment variables. See git-commit-tree(1).

user.signingkey
    If git-tag(1) or git-commit(1) is not selecting the key you want it to automatically when creating a signed tag or commit, you can override the default selection with this variable. This option is passed unchanged to gpg’s --local-user parameter, so you may specify a key using any method that gpg supports.

web.browser
    Specify a web browser that may be used by some commands. Currently only git-instaweb(1) and git-help(1) may use it.
