man git-get-tar-commit-id (Commandes) - Extract commit ID from an archive created using git-tar-tree.
NAME
git-get-tar-commit-id - Extract commit ID from an archive created using git-tar-tree.
SYNOPSIS
git-get-tar-commit-id < <tarfile>
DESCRIPTION
Acts as a filter, extracting the commit ID stored in archives created by git-tar-tree. 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-tar-tree or if the first parameter of git-tar-tree had been a tree ID instead of a commit ID or tag.
