You may not be familiar with the mall, but that shouldn't be a problem. Why not? Because of the maps, which you can usually find near all the major entrances to the mall. The same can be said for your Red Hat Linux system: Navigation's easy once you know where you're going. Tip: Make sure you've logged into your user account! Remember that unless you like to live on the wild - and dangerous - side, using a root account for all your activities is toying with disaster. If you didn't create your user account at the time of your Red Hat Linux installation and haven't done so now, please do so now. Turn to Chapter 2 if you require assistance on how to create your user account. Finding Yourself with pwd Sooner or later (probably sooner), when you start looking through directories, you're bound to ask, "Where the heck am I?" And you won't be speaking philosophically.
