hg-ssh - a wrapper for ssh access to a limited set of mercurial repos
|
|
|
|
|
|
To be used in ~/.ssh/authorized_keys with the "command" option, see sshd(8):
|
|
|
command="hg-ssh path/to/repo1 /path/to/repo2 ~/repo3 ~user/repo4" ssh-dss ...
|
|
|
(probably together with these other useful options:
|
|
|
no-port-forwarding,no-X11-forwarding,no-agent-forwarding)
|
|
|
|
|
|
This allows pull/push over ssh to to the repositories given as arguments.
|
|
|
|
|
|
If all your repositories are subdirectories of a common directory, you can
|
|
|
allow shorter paths with:
|
|
|
command="cd path/to/my/repositories && hg-ssh repo1 subdir/repo2"
|
|
|
|
|
|
You can use pattern matching of your normal shell, e.g.:
|
|
|
command="cd repos && hg-ssh user/thomas/* projects/{mercurial,foo}"
