Summary: Indispensable!
Review: This book isn't going to teach you UNIX. If you're already familiar with UNIX, though, this book is an essential part of any IT reference library.

Summary: The ultimate "Desktop Reference "
Review: This book sits within 12" of me whenever I am at work. I am an administrator of an AIX system and this book has proven to be an invaluable reference. This is not a guide for the light at heart but should be used as one would use a dictionary.

Summary: Quality from house O'Reilly
Review: This handbook is one of the best from O'Reilly. It was one of the first I bought. It is complete reference with all UNIX commands and options. Most of the commands have long descriptions and examples. Chapter 2 containing the alphabetical summary of commands, is the most interesting and used. This is truely the best UNIX instructor for everybody, although it is important to say that beginners will have problems to understand it! They must get a little UNIX experience first!Virgilio Krumbacher

Summary: Another brilliant book from the O'Reilly crew.
Review: This is a must have book for anyone using Unix. It is a wonderful reference book. The book takes you through the basic commands for Unix. The commands are listed alphabetically and for each command you get a desciption, the common switches and an example of how to use it. From there it gives you an overview of a shell and provides specifics about teh Bourne and Korn shells. Sections on VI, AWK, SED, and emacs round out this incredible book. All in all I found this to be one of the most useful reference manuals I have. It's a must have book for any UNIX user.

Summary: Best Unix book on the market
Review: This is a must have book for anyone working on or near a Unix system. It's a life saver and a time saver. There is always enough information to jog your memory and help you get the job done. This book is not for a first timer. Rather it's for someone that already knows Unix and needs a handy "reminder" from time to time.

Summary: A superior UNIX reference book
Review: This is a very good reference book. I use it almost daily. But it is almost completely useless for the poor novice. It is like a dictionary, which, if you do not know the language, you cannot look up the word, if you do not know what you want to do, you will have a hard time finding the command. If you are a novice and you are stuck with having to work in a LUNIX environment, you should probaby have this book anyway because, eventually, it will become useful to you. Just pick up a good book on shell programming while you're at it. One that provides a lot of examples and is probably somewhat specific to the shell you will be using. I'd have given this five stars, but I don't like the new cover. Search the used books stores for the classic blue cover with the referee.

Summary: great in parts, a lot of filler
Review: This is one of two unix books I recommend. Each have their own strengths. In UNIX IN A NUTSHELL, the shell sections are great--you get enough about common features, then the unique parts of csh/ksh/sh, with a few nice examples thrown in. The dictionary of commands is super--though if you don't know what you are looking for you won't find it. (in this case, try UNIX POWER TOOLS, it has a GREAT index) One way to use the dictionary is to just read through it now and then and let the commands sink in to your brain over time, another is to kind of hunt through, speedreading-style. The big waste of space are the sections on troff and nroff and other ancient utilities that haven't been used in years (modern humans use perl). They appear to have been put in to take up space. Overall though, the book is great to have.

Summary: Practical. Always by my side.
Review: This is the book I always turn to when I have a UNIX question. No other book has so much jam-packed information. It is clearly organized. The one problem with this new edition is they dropped the command summaries for the different debuggers. This was invaluable. The lack of this section drops the book from 5 stars to 3 stars. Also the stuff on troff, mm, etc., is just a waste. I haven't seen anyone use those dinosaurs in a while. It would have been better to include coverage of HTML/XML and possibly framemaker. A section on perl would be handy as well.

Summary: Excellent reference
Review: This is the first book to go to for unix syntax. It contains everything you need on Unix commands. It's the Unix Bible as far as I'm concerned.
