As far back as I can remember I have had UNIX around. My bed time stories were about it and the first words out of my mouth were 'UNIX is cool'. Well, maybe not the first words, but I have been around the UNIX systems my entire professional career. I figure it is just as close.

I have one more confession to make. Lately I have been getting tired of seeing a thousand pages or longer for introductory books on UNIX and Linux or practical guides that are anything but practical. All these books give UNIX a reputation for being extremely difficult to learn and use. Would you want to read a thousand page practical or introductory book? No? I can't blame you. I wouldn't want to read it either.

I hope that this book will change your mind about UNIX. It will arm you with a true practical knowledge of UNIX. Knowledge which will serve as your guide and as your reference. Enjoy it and happy journey!

This edition adds and updates Linux specific commands.
It is pocket size and it is for the rest of us!
