http://ubuntuforums.org – hi i'm new to this and i was wondering if anyone could help me. i want to make a menu style shell script that will let me backup, restore and quit and i have no idea how to even start. I've read many tutorials but it goes over my head :sad: hope someone can help. i really haven't a clue what to do to even start writing this and would love to learn. surely someone knows how to make one like this (Hardware)
