Praise for the First Edition of A Practical Guide to Linux Commands, Editors, and Shell Programming First Sobell taught people how to use Linux!now he teaches you the power of Linux. A must-have book for anyone who wants to take Linux to the next level. --Jon maddog Hall, Executive Director, Linux International This book is a very useful tool for anyone who wants to 'look under the hood' so to speak, and really start putting the power of Linux to work. What I find particularly frustrating about man pages is that they never include examples. Sobell, on the other hand, outlines very clearly what the command does and then gives several common, easy-tounderstand examples that make it a breeze to start shell programming on one's own. As with Sobell's other works, this is simple, straight-forward, and easy to read. It's a great book and will stay on the shelf at easy arm's reach for a long time. --Ray Bartlett, Travel Writer Overall I found this book to be quite excellent, and it has earned a spot on the very front of my bookshelf. It covers the real 'guts' of Linux--the command line and its utilities--and does so very well. Its strongest points are the outstanding use of examples, and the Command Reference section. Highly recommended for Linux users of all skill levels. Well done to Mark Sobell and Prentice Hall for this outstanding book! --Dan Clough, Electronics Engineer and Slackware Linux user Totally unlike most Linux books, this book avoids discussing everything via GUI and jumps right into making the power of the command line your friend. --Bjorn Tipling, Software Engineer, ask.com This book is the best distro-agnostic, foundational Linux reference I've ever seen, out of dozens of Linux-related books I've read. Finding this book was a real stroke of luck. If you want to really understand how to get things done at the command line, where the power and flexibility of free UNIX-like OSes really live, this book is among the best tools you'll find toward that end. --Chad Perrin, Writer, TechRepublic Praise for Other Books by Mark G. Sobell I keep searching for books that collect everything you want to know about a subject in one place, and keep getting disappointed. Usually the books leave out some important topic, while others go too deep in some areas and must skim lightly over the others. A Practical Guide to Red Hat(R) Linux(R) is one of those rare books that actually pulls it off. Mark G. Sobell has created a single reference for Red Hat Linux that can't be beat! This marvelous text (with a 4-CD set of Linux Fedora Core 2 included) is well worth the price. This is as close to an 'everything you ever needed to know' book that I've seen. It's just that good and rates 5 out of 5. --Ray Lodato, Slashdot contributor Mark Sobell has written a book as approachable as it is authoritative. --Jeffrey Bianchine, Advocate, Author, Journalist Excellent reference book, well suited for the sysadmin of a Linux cluster, or the owner of a PC contemplating installing a recent stable Linux. Don't be put off by the daunting heft of the book. Sobell has strived to be as inclusive as possible, in trying to anticipate your system administration needs. --Wes Boudville, Inventor A Practical Guide to Red Hat(R) Linux(R) is a brilliant book. Thank you Mark Sobell. --C. Pozrikidis, University of California at San Diego This book presents the best overview of the Linux operating system that I have found... [It] should be very helpful and understandable no matter what the reader's background: traditional UNIX user, new Linux devotee, or even Windows user. Each topic is presented in a clear, complete fashion, and very few assumptions are made about what the reader knows... The book is extremely useful as a reference, as it contains a 70-page glossary of terms and is very well indexed. It is organized in such a way that the reader can focus on simple tasks without having to wade through more advanced topics until they are ready. --Cam Marshall, Marshall Information Service LLC, Member of Front Range UNIX Users Group [FRUUG], Boulder, Colorado Conclusively, this is THE book to get if you are a new Linux user and you just got into the RH/Fedora world. There's no other book that discusses so many different topics and in such depth. --Eugenia Loli-Queru, Editor in Chief, OSNews.com
