Summary: Buy this one. Don't look at the price.
Review: This, when combined with O'Reilly's _Unix in a Nutshell_ will provide the reader with not only the 'how' of unix system administration, but the 'why' as well. Honest, insightful, witty, and frequently dead-on-target in a zen sort of way, the third edition of this book is a treasured reference, and a good read while applying patches. I own two copies; one for home and one for the office. I have given this book as a Christmas gift to other unix administrators. It's that good.

Summary: A excellent book for new and experienced unix administrator
Review: A very excellent reference book for new and experienced unix administrator, which use FREE BSD, LINUX, HP-UNIX and SOLARIS as an example and cover both basic and advanced topics in clear english.

Summary: A true classic - essential if you manage multi-platforms.
Review: This is a true classic and pretty much the only general Unix sysadmin book you will ever need. The sections on DNS and sendmail are thorough and precise (the sendmail section is so good you do not need the sendmail O'Reilly "bat" book anymore). It covers almost every single aspect of system admin, has humour and is strongly opinionated.
The real strength is that it uses examples from the 4 most important Unix's in todays market. If you know how to configure networking under Linux and need to know how to do it under Solaris then this book is for you.Some might have wanted AIX instead of FreeBSD, and vanilla Linux instead of RedHat: I think the choice of covering RedHat, FreeBSD, Solaris and HP/UX is spot on (as is the whole book). It's _the best Unix sysadmin _ book out there (forget about the cd-rom: it's not needed).

Summary: Best book for learning the core fundamentals
Review: You can't afford to be without this book if you develop or maintain networks. This is or should be as much a classic as K&R's "C a Programming Language" is to serious programmers.
Rating:
Summary: Strong cross-platform reference.
Review: I have thousands of dollars in computer books. And as a network security analyst, I used most of them often. But I carry this book in my bag all the time. Since I work in a mixed environment, this book proves invaluable in helping me tackle Solaris, Linux and HP-UX issues. I have not seen another book that covers so much so well in less than 1000 pages. If you use unix, get this book. It will be among your top 5 books in the "best money spent" category!

Summary: The Pauli for Unix system admins
Review: When chef's in Holland learn to cook there is only one book they will use to learn the different techniques. The same goes for this book. Every Linux/BSD/UNIX administrator must have this book in his back of goodies (next to the perl cookbook offcourse). The content of the book explaines every basic and advanced technique needed to administret, set-up or manage systems from 1 to severel hundreds. It gives usefull tips, very good hints and also educates in good unix practice. We at Nebula give all our new staff members this book and give them 3 weeks time to study it before taking an exam in it. There is one thing to say about the book and that is that it currently explaines redhat 6.x release. Due to the various changes in the Redhat 7.x releases an update (or extra release) would be very welcome. as example: Xinetd is not explained yet in the book but that will def. happen in the fourth release for which we can't wait for to get our hands on.. Problem.. it's not out yet.. :-) So dear new guy in the unix world, and old chap. Yes A deffinate buyer!!

Summary: Excellent System Administration Book!
Review: This book should be on the bookshelf of every System Administrator. In fact, you're not even qualified to be an Admin without this book. It gives actual experience and opinions, both of which are sorely lacking from most computer books. If all you want is a restatement of the man pages, this book is probably not for you. However, if you want actual insight on not only how to do the job, but how to do it well, this book is for you! Highest recommendations.

Summary: what hasn't been said?
Review: All aspiring unix system administrators - this book should definitely be your starting point. Thorough, intelligent, and even humourous. 600 thumbs up.
Rating:
Summary: One of the best
Review: This is the best book to keep handy along with UNIX in a nutshell, and maybe Essential System Administration with something for your favorite flavor of scripting and/or SQL. Again, this is one of my most tattered books and travels with mealways. I can't count how many times it has saved my life and hours of looking elsewhere, even with internet access. Truly essential. GET THIS BOOK! I have the Red cover (2nd ed.), and the only thing it didn't cover was AIX, but then there's always smit.

Summary: If you can have only one Unix admin book....
Review: The seminal work in the field. If you can have only one Unix administration book, this should be it. This book broadly covers a number of different versions of Unix, and doesn't go into as much depth as some other books may, but all the essential topics are covered, and with real-world practical advice.
