Somewhat similar to "svn info" but for a Git checkout

git-info.sh

#!/bin/bash

#
# Displays information about the current working copy of a Git checkout
# and how it relates back to the remote branch it is tracking (if there is one)

Example output:

Working Copy Root Path: /Users/jcaddel/git/rice-git
                Remote: origin
            Remote URL: https://github.com/jcaddel/rice-git.git
                Branch: master
     Last Local Commit: 4bc1075bb9b0fa330082809b91faf8f7dd4a5520 (11 hours ago)
    Last Remote Commit: 4bc1075bb9b0fa330082809b91faf8f7dd4a5520 (11 hours ago)
          Synchronized: true

adding

cd `readlink -f .`

before

while [ ! -d .git ] && [ ! `pwd` = "/" ]; do cd ..; done

allows you to find the real "Working Copy Root Path".
