Usage "source forkops.sh [repo-name]". I wanted to fork opscode community recipes, but forking outside of github is a little difficult so I made this script.

forkops.sh

dir=$1
if [ "$dir" == "" ] ; then
    echo "What are we forking?"
    read dir
fi
url=https://github.com/opscode-cookbooks/$dir
git init --bare $dir.git
cd $dir.git
git remote add opscode $url --fetch
git for-each-ref --format='%(refname:short)' -- 'refs/remotes/opscode/' |     while read ref; do git branch -t "$(basename "$ref")" "$ref"; done
cd ..
echo "Done"

Revision 2, added .git to the end of the folder, as is convention
