bb-change-url

#!/bin/bash
#
# This utility creates a bitbucket URL for showing the changes between the last two tags for the
# git repo you are currently in. 
#
# To install this place this file in your /usr/local/bin folder and 
# chmod +x the file so it has execution rights. Then run 'bb-change-url' from any git repo.
