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
