Poor man's github

Key points of this article:

• Build a github prototype written in Bash within 5 minutes
• Highlight key elements in my usual git work flow
• Git is scalabe. you can use any tool to extend it.

As Yuri Albuquerque mentioned, there are more powerful tools like gitolite. But the key concept behind the system is similar.

Add following code into ~/.bashrc and run "source ~/.bashrc", then run "gih" to see help:

function gih() {
    local MY_USERNAME=git
    local MY_SSH_URL=git@domain.name
    local MY_SSH_PORT=8888
    if [ -z "$1" ]; then
        cat << 'EOF'
Usage: gih [command]
Commands:
l, ls, list - list the projects
n, new [project-name] - create a new project
r, readme [project-name] - show README
i, issue [project-name] - show issues list
st, status - check free space of git server
u, url [project-name] - the full url of the project
EOF

        case $1 in
