NAME


git-shell - Restricted login shell for Git-only SSH access

SYNOPSIS


chsh -s $(command -v git-shell) <user>
git clone <user>@localhost:/path/to/repo.git
ssh <user>@localhost

DESCRIPTION


This is a login shell for SSH accounts to provide restricted Git access. It permits
execution only of server-side Git commands implementing the pull/push functionality, plus
custom commands present in a subdirectory named git-shell-commands in the user’s home
directory.

COMMANDS


git shell accepts the following commands after the -c option:

git receive-pack <argument>, git upload-pack <argument>, git upload-archive <argument>
Call the corresponding server-side command to support the client’s git push, git
fetch, or git archive --remote request.

cvs server
Imitate a CVS server. See git-cvsserver(1).

If a ~/git-shell-commands directory is present, git shell will also handle other, custom
commands by running "git-shell-commands/<command> <arguments>" from the user’s home
directory.

INTERACTIVE USE


By default, the commands above can be executed only with the -c option; the shell is not
interactive.

If a ~/git-shell-commands directory is present, git shell can also be run interactively
(with no arguments). If a help command is present in the git-shell-commands directory, it
is run to provide the user with an overview of allowed actions. Then a "git> " prompt is
presented at which one can enter any of the commands from the git-shell-commands
directory, or exit to close the connection.

Generally this mode is used as an administrative interface to allow users to list
repositories they have access to, create, delete, or rename repositories, or change
repository descriptions and permissions.

If a no-interactive-login command exists, then it is run and the interactive shell is
aborted.

EXAMPLE


To disable interactive logins, displaying a greeting instead:

$ chsh -s /usr/bin/git-shell
$ mkdir $HOME/git-shell-commands
$ cat >$HOME/git-shell-commands/no-interactive-login <<\EOF
#!/bin/sh
printf '%s\n' "Hi $USER! You've successfully authenticated, but I do not"
printf '%s\n' "provide interactive shell access."
exit 128
EOF
$ chmod +x $HOME/git-shell-commands/no-interactive-login
