Check git status of multiple repos

If you're like me you have a dir like ~/Workspace/Github where all your git repos live. I often find myself making a change in a repo, getting side tracked and ending up in another repo, or off doing something else all together. After a while I end up with several repos with modifications. This script helps me pick up where I left off by checking the status of all my repos, instead of having to check each one individually.

Usage:

git-status [directory]

This will run git status on each repo under the directory specified. If called with no directory provided it will default to the current directory.
