It sure will but that's just what he needs until he can get a new OS disk.I checked what the script does:

Hey guys,
I got my first mac today so really happy about that. I bought it second hand and there is a fair amount of this guys stuff on here that I guess I would like to can. I am thinking of doing a re install. I got all the disks with the book so that is not the problem. I am a windows man so never done a restore on a mac. Is it a simple procedure? I am probably being a little lazy and should google a bit more, but its late and I would rather be playing with my new toy
Thanks, Grim
