What Others Think

What is the [-t 0] for? It does not seem to be doing anything. Also I would add some "||exit" after the sudo command as it will otherwise just run the command if you press enter 3 times.

houghi: It checks to see if STDIN is a terminal. If it is, sudo will work. Otherwise, it's probably a GUI application and will need gksu.
