Unix and Linux System Administration Handbook 4th Edition

As an author, editor, and publisher, I never paid much attention to the competitionexcept 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
