Using this Guide

"Under Linux there are GUIs (graphical user interfaces), where you can point and click and drag, and hopefully get work done without first reading lots of documentation. The traditional Unix environment is a CLI (command line interface), where you type commands to tell the computer what to do. That is faster and more powerful, but requires finding out what the commands are." -- from man intro(1)

This guide will make you familiar with basic GNU/Linux shell commands. It is not intended to be a complete guide to the command line, just an introduction to complement Ubuntu's graphical tools.
