Licence

Licence should be GPLv3 in a file named "COPYING" and referenced at the top of each file.

;-)

Right you are! I'll fix that (I'm new to this). How would you reference it in the file itself?

[rheaplex]

It's heavy for a short script, but the top of the file should look like (with obvious modification):

#!/bin/bash
# script.sh - A script to do something I describe here

Why every file? Cannot the one licence file reference each script?

[rheaplex]

Scripts reference the license, not vice versa. See here:

If you want to just put "Copyright 2013 , License: GPL v3+" at the top of each file I'm not sure how sound that is legally but I've seen it in e.g. Python files.
