I cannot take credit for this tutorial, as I learned it from another site. All credit goes to the guy at Ubuntu Geek. I simply want to show others how to, who may be a Linux noob like myself. I can provide the source link if anyone is interested. Alright, lets get started.

With the terminal open type the following command:
You may or may not be prompted to type in your password
