README.md

Run your own remote server that you can ssh to? You can use it to host your own private git repositories - they're just directories that have been git init --bare.

Use this script to create new remote repositories, list existing and get simple help for cloning or adding them as remotes.

Save this script to the remote server (e.g. ~/bin/repo-man.sh), and then invoke from your local machine like this:

ssh -t [email protected] "~/bin/repo-man.sh"

The -t is important, as it attaches a TTY to the ssh session.

repo-man.sh

#!/bin/bash
#
# Makes a repo, tells you how to clone it. You're mustard!
