If you are new to Unix, this concise book will tell you just what you need to get started and no more. Unix was one of the first operating systems written in C, a high-level programming language, and its natural portability and low price made it a popular choice among universities. Initially, two main dialects of Unix existed: one produced by AT&T known as System V, and one developed at UC Berkeley and known as BSD. In recent years, many other dialects have been created, including the highly popular Linux operating system and the new Mac OS X (a derivative of BSD). Learning the Unix Operating System is a handy book for someone just starting with Unix or Linux, and it's an ideal primer for Mac and PC users of the Internet who need to know a little about Unix on the systems they visit. The fifth edition is the most effective introduction to Unix in print, covering Internet usage for email, file transfers, web browsing, and many major and minor updates to help the reader navigate the ever-expanding capabilities of the operating system:

• In response to the popularity of Linux, the book now focuses on the popular bash shell preferred by most Linux users.

• Since the release of the fourth edition, the Internet and its many functions has become part of most computer user's lives. A new chapter explains how to use ftp, pine for mail, and offers useful knowledge on how to surf the web.

• Today everyone is concerned about security. With this in mind, the author has included tips throughout the text on security basics, especially in the Internet and networking sections.

The book includes a completely updated quick reference card to make it easier for the reader to access the key functions of the command line.

Excellent Beginner Book! - 2007-03-20

I didn't know anything about Unix at all. After reading the reviews here, I decided on this book. It's for beginners like me. After finishing the book and practicing the exercises, I believe that I'm ready to go to the next level. And I didn't need any over-priced DVDs to go with it (and neither do you!)

Good stuff to start with - 2007-04-12

This book is a great book to start-up on your Unix commands. The examples re-iterate their meaning and I think this book is a great start to the world of Unix.

The X Win discussion though I thought could have been at the end of the book instead of the beginning.

Perfect for Linux beginners - 2009-06-20
Reviewer Rating:
This book is absolutely perfect for Linux beginners who are yet to become familiar with the command line environment. I got this book when I was a college freshman, and even now, when I am in grad school, I often find myself going through it for a quick reference.

However, if you are looking for a deep detailed UNIX guide, then this would not serve your purpose.

I wouldn't if I were you - 2008-09-15

This was an optional text for an Intro Unix/Linux course. I am so glad the required book is a lot better than this one. Some of the code samples are in the paragraphs and it is hard to tell what is text and what is a unix command. If I only had this text, I doubt I could get through the class. It provides no new information.
