+.TH LSLOGINS "1" "April 2014" "util-linux" "User Commands"

+.SH NAME

+lslogins \- display information about known users in the system

+.SH SYNOPSIS

+.B lslogins

+[\fIoptions\fR] [\fB-s\fR|\fB-u\fR[=\fIUID\fR]] [\fB-g \fIgroups\fR] [\fB-l \fIlogins\fR]

+.SH DESCRIPTION

+.PP

+Examine the wtmp and btmp logs, /etc/shadow (if necessary) and /etc/passwd

+and output the desired data.

+.PP

+The default action is to list info about all the users in the system.

+.SH OPTIONS

+Mandatory arguments to long options are mandatory for short options too.

+.TP

+\fB\-a\fR, \fB\-\-acc\-expiration\fR

+Display data about the date of last password change and the account expiration

+date (see \fBshadow\fR(5) for more info).  (Requires root priviliges.)

+.TP

+\fB\-\-btmp\-file \fIpath\fP

+Alternate path for btmp.

+.TP

+\fB\-c\fR, \fB\-\-colon\-separate\fR

+Separate info about each user with a colon instead of a newline.

+.TP

+\fB\-e\fR, \fB\-\-export\fR

+Output data in the format of NAME=VALUE.

+.TP

+\fB\-f\fR, \fB\-\-failed\fR

+Display data about the users' last failed login attempts.

+.TP

+\fB\-G\fR, \fB\-\-groups\-info\fR

+Show information about groups.

+.TP

+\fB\-g\fR, \fB\-\-groups\fR=\fIgroups\fR

+Only show data of users belonging to \fIgroups\fR.  More than one group

+may be specified; the list has to be comma-separated.

+.TP

+\fB\-h\fR, \fB\-\-help\fR

+Display help information and exit.

+.TP

+\fB\-L\fR, \fB\-\-last\fR

+Display data containing information about the users' last login sessions.

+.TP

+\fB\-l\fR, \fB\-\-logins\fR=\fIlogins\fR

+Only show data of users with a login specified in \fIlogins\fR (user names or user

+IDS).  More than one login may be specified; the list has to be comma-separated.

+.TP

+\fB\-m\fR, \fB\-\-supp\-groups\fR

+Show supplementary groups.

+.TP

+\fB\-n\fR, \fB\-\-newline\fR

+Display each piece of information on a separate line.

+.TP

+\fB\-\-noheadings\fR

+Do not print a header line.

+.TP

+\fB\-\-notruncate\fR

+Don't truncate output.

+.TP

+\fB\-o\fR, \fB\-\-output \fIlist\fP

+Specify which output columns to print.  Use

+.B \-\-help

+to get a list of all supported columns.

+.TP

+\fB\-p\fR, \fB\-\-pwd\fR

+Display information related to login by password (see also \fB\-afL).

+.TP

+\fB\-r\fR, \fB\-\-raw\fR

+Raw output (no columnation).

+.TP

+\fB\-s\fR, \fB\-\-system\-accs\fR[=\fIthreshold\fR]

+Show system accounts.  These are by default all accounts with a UID below 1000

+(non-inclusive), with the exception of either nobody or nfsnobody (UID 65534).  The UID

+threshold can also be specified explicitly (necessary for some distributions that

+allocate UIDs starting from 100, 500 - or an entirely different value - rather than 1000).

+.TP

+\fB\-\-time-format\fR \fItype\fP

+Display dates in short, full or iso format.  The default is short, this time

+format is designed to be space efficient and human readable.

+.TP

+\fB\-u\fR, \fB\-\-user\-accs\fR[=\fIthreshold\fR]

+Show user accounts.  These are by default all accounts with UID above 1000

+(inclusive), with the exception of either nobody or nfsnobody (UID 65534).  The UID

+threshold can also be specified explicitly (necessary for some distributions that

+allocate UIDs starting from 100, 500 - or an entirely different value - rather than 1000).
