As an author, editor, and publisher, I never paid much attention to the competition-except in a few cases. This is one of those cases. The UNIX System Administration Handbook is one of the few books we ever measured ourselves against. -From the Foreword by Tim OReilly, founder of OReilly Media This book is fun and functional as a desktop reference. If you use UNIX and Linux systems, you need this book in your short-reach library. It covers a bit of the systems history but doesnt bloviate. Its just straightfoward information delivered in colorful and memorable fashion. -Jason A. Nunnelley This is a comprehensive guide to the care and feeding of UNIX and Linux systems. The authors present the facts along with seasoned advice and real-world examples. Their perspective on the variations among systems is valuable for anyone who runs a heterogeneous computing facility. -Pat Parseghian The twentieth anniversary edition of the worlds best-selling UNIX system administration book has been made even better by adding coverage of the leading Linux distributions: Ubuntu, openSUSE, and RHEL.
