"This tutorial is the first in a series of introductory Linux lessons. This first article will cover navigating around a Linux filesystem along with a brief passage--with examples--on using ten of the most essential GNU/Linux commands.
"You should have access to a Linux system in order to perform the example commands as we progress through the tutorial. If you don't have a dedicated Linux box, you can use a Live Linux CD-ROM-based distribution such as Knoppix. Knoppix will let you run Linux directly from the CD without modifying anything on your hard drive.
"Once you're logged in to a Linux system, open a terminal session. Each of the commands covered here will be typed directly into a command line terminal window. Under Red Hat Linux, terminal is found in the 'system tools' section of the menu. (Your system may, alternatively, have a terminal program called 'konsole', 'xterm', or 'shell'. Look around your system for a menu with 'tools' or 'utilities' in the name if necessary...)"
