UNIX Commands
Unveiled

By the Q

This file is to help you out on all those hard UNIX commands. Heh, heh.  In the white is what you type at the prompt.  Hopefully you know what the prompt is.  In the green is what it does.  Anything in red can and should be changed to fit your needs.  I just wrote these as they came to me so they are not in any order.  Good luck.
