This script is a bash script to run on a freshly installed Ubuntu system that will automatically upgrade the current system to the newest release as well as remove all of the 'bloatware', or unwanted programs that come along with a default Ubuntu install.
Get the file...
wget https://raw.githubusercontent.com/mfitzgerald2/UbuntuSetupScript/master/USS.sh

The bloatware removal code was adapted from Nick Seagull.
