# Simple script for shutting down the raspberry Pi at the press of a button.

# Setup the Pin with Internal pullups enabled and PIN in reading mode.

# Our function on what to do when the button is pressed

The "&" at the end of the command tells it to run the process in the background. If you omit it, then your login prompt probably will not appear.
