When formatted as a man page, 1st section header is always in upper case even if we write it otherwise. Make all 1st section headers uppercase to keep it close to the final output. This does affect html since case is kept there, but I still think it's a good idea to maintain a consistent style for 1st section headers. Some sections perhaps should become second sections instead, where case is kept, and for better organization. I will update if anyone has suggestions about this. While at there I also make some header more consistent (e.g. examples vs example) and fix a couple minor things here and there.

NAME
|
|
----
|
|
git-shell - Restricted login shell for Git-only SSH access
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'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 linkgit: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.
|
|
|
|
EXAMPLES
|
|
--------
|
|
|
|
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
|
|
----------------
|
|
|
|
To enable git-cvsserver access (which should generally have the
|
|
`no-interactive-login` example above as a prerequisite, as creating
|
|
the git-shell-commands directory allows interactive logins):
|
|
|
|
----------------
|
|
$ cat >$HOME/git-shell-commands/cvs <<\EOF
|
|
if ! test $# = 1 && test "$1" = "server"
|
|
then
|
|
echo >&2 "git-cvsserver only handles \"server\""
|
|
exit 1
|
|
fi
|
|
exec git cvsserver server
|
|
EOF
|
|
$ chmod +x $HOME/git-shell-commands/cvs
|
|
