# git-get-tar-commit-id(1) Manual Page

## NAME

git-get-tar-commit-id - Extract commit ID from an archive created using git-archive

## SYNOPSIS

    git get-tar-commit-id < <tarfile>

## DESCRIPTION

Acts as a filter, extracting the commit ID stored in archives created by git archive. It reads only the first 1024 bytes of input, thus its runtime is not influenced by the size of <tarfile> very much.

If no commit ID is found, git get-tar-commit-id quietly exists with a return code of 1. This can happen if <tarfile> had not been created using git archive or if the first parameter of git archive had been a tree ID instead of a commit ID or tag.
