Guide to UNIX Using Linux, Third Edition is a hands-on, practical guide that teaches the fundamentals of the UNIX operating system concepts, architecture and administration. These concepts are taught using Linux, a free, PC-compatible UNIX clone that is an ideal teaching tool for many basic and advanced UNIX commands. The power, stability, and flexibility of UNIX has contributed to its popularity in mission-critical business and networking applications.
This book will teach you the basics of maneuvering around the shell and some basic shell programming, but it does so using very narrow examples that you have to follow along with quite dogmatically, rather than giving you the tools that help build your confidence. Also, some of the examples are just plain incorrect which is frustrating. I'm certain there are better texts out there.
