git-shell(1)

git-shell -c <command> <argument>

This is meant to be used as a login shell for SSH accounts you want to restrict to GIT pull/push access only. It permits execution only of server-side GIT commands implementing the pull/push functionality. The commands can be executed only by the -c option; the shell is not interactive.

Currently, only the git-receive-pack and git-upload-pack commands are permitted to be called, with a single required argument.
