A Practical Guide to Linux Commands, Editors, and Shell Programming

Praise for Mark Sobell’s Books

“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® Linux® is one of those rare books that actually pulls it off. Mark G. Sobell has created a single reference for Red Hat Linux that cannot 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 striven to be as inclusive as possible, in trying to anticipate your system administration needs.”
―Wes Boudville, Inventor“A Practical Guide to Red Hat® Linux® 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 is: 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 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.comThe Most Useful Linux Tutorial and Reference Ever, with Hundreds of High-Quality Examples Covering Every Linux Distribution!

To be truly productive with Linux, you need to thoroughly master the shells and the command line. Until now, you had to buy two books to gain that mastery: a tutorial on fundamental Linux concepts and techniques, plus a separate reference. Worse, most Linux references offer little more than prettied-up man pages. Now, there’s a far better solution. Renowned Linux expert Mark Sobell has brought together comprehensive, insightful guidance on the tools system administrators, developers, and power users need most, and an outstanding day-to-day reference, both in the same book.

This book is 100 percent distribution and release agnostic: You can use it on any Linux system, now and for years to come. What’s more, it’s packed with hundreds of high-quality examples: better examples than you’ll find in any other Linux guidebook. This is Linux from the ground up: the clearest explanations and most useful knowledge about everything from filesystems to shells, editors to utilities, and programming tools to regular expressions. And when you need instant answers, you’ll constantly turn to Sobell’s comprehensive command reference section―organized and tabbed for easy, fast access!

Don’t settle for yesterday’s Linux guidebook. Get the one book that meets today’s challenges―and tomorrow’s!
