How do I use the RHEL operating system (the operating system on all of the public workstations)?

RHEL (Red Hat Enterprise Linux) is a modified version of the Fedora Linux distibution. This guide, written by the people at Canonical (the creators of the Ubuntu Linux operating system), provides a very brief history of how Linux came to be. It also gives an overview of how to use the command line. Please be aware that, while this tutorial covers command line tools that can be used on almost any OS in the Linux family, the workstations administered by the Systems Office run RHEL – not Ubuntu.
