OK 99% of people here absolutely do not need this script.
Admittedly, I am one of the few who cannot seem to remember the code to add a ppa.
Every time I need to click the little tab about installing software just be be reminded about what to put before the name of the ppa.
So I came up with a script to make my life easier. I made a quicklist to launch it and have it in that side dock like thing Unity uses.

echo "This script is for adding a ppa"
read -p "Enter the PPA name: " var2
sudo apt-get update
read -p "Enter the name of the software to install. " var4
sudo apt-get install $var4
