Unix Reference Guide
Unless you have a Unix machine sitting on your desktop, you're probably accessing it through telnet or a command-line shell. This interface may be a little intimidating to new users who are usually a tad more comfortable with a point-and-click interface. But it's really not as hard as it looks.
This reference sheet gives you the basic commands you'll need, focusing especially on file management. You can also learn how to combine commands and become a real power user. If you need more help getting started, take a look at Pam's excellent introduction entitled "Enough Unix for Your Résumé." Between that article and this guide, you'll be on your way to becoming a Unix master. Soon you'll be wondering how you got along without it.
