6 git-shell - Restricted login shell for Git-only SSH access
12 'chsh' -s $(command -v git-shell) <user>
13 'git clone' <user>`@localhost:/path/to/repo.git`
14 'ssh' <user>`@localhost`
19 This is a login shell for SSH accounts to provide restricted Git access.
20 It permits execution only of server-side Git commands implementing the
21 pull/push functionality, plus custom commands present in a subdirectory
22 named `git-shell-commands` in the user's home directory.
27 'git shell' accepts the following commands after the '-c' option:
29 'git receive-pack <argument>'::
30 'git upload-pack <argument>'::
31 'git upload-archive <argument>'::
32 Call the corresponding server-side command to support
33 the client's 'git push', 'git fetch', or 'git archive --remote'
36 If a `~/git-shell-commands` directory is present, 'git shell' will
37 also handle other, custom commands by running
38 "`git-shell-commands/<command> <arguments>`" from the user's home
44 By default, the commands above can be executed only with the '-c'
45 option; the shell is not interactive.
47 If a `~/git-shell-commands` directory is present, 'git shell'
48 can also be run interactively (with no arguments). If a `help`
49 command is present in the `git-shell-commands` directory, it is
50 run to provide the user with an overview of allowed actions. Then a
51 "git> " prompt is presented at which one can enter any of the
52 commands from the `git-shell-commands` directory, or `exit` to close
55 Generally this mode is used as an administrative interface to allow
56 users to list repositories they have access to, create, delete, or
57 rename repositories, or change repository descriptions and
60 If a `no-interactive-login` command exists, then it is run and the
61 interactive shell is aborted.
66 To disable interactive logins, displaying a greeting instead:
69 $ chsh -s /usr/bin/git-shell
70 $ mkdir $HOME/git-shell-commands
71 $ cat >$HOME/git-shell-commands/no-interactive-login <<\EOF
73 printf '%s\n' "Hi $USER! You've successfully authenticated, but I do not"
74 printf '%s\n' "provide interactive shell access."
77 $ chmod +x $HOME/git-shell-commands/no-interactive-login
