Praise for Mark Sobell's Books "If you want to become a real Linux guru, this is one of the better books available. Readable, straightforward, educational, it is a superb reference that blends the educational aspect of a typical book on learning Linux with a typical book of command line references. I highly recommendA Practical Guide to Linux ® Commands, Editors, and Shell Programming." Harold D. McFarland, Editor, Readers Preference Reviews "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 the RH/Fedora world. There's no other book that discusses so many different topics and in such depth."
