Startup Shutdown Button Pi

[TheDutypaid]

At the moment when I power on I plug in my Pi and when power off, I go through the shutdown menu.

I was reading this RetroPie Shutdown and Startup Switch – The Easy Way

The install is from a script

Code:

curl http://pie.8bitjunkie.net/shutdown/setup-shutdown.sh | bash

Would this work with Xbian?
