1. This book contains many errors like other readers have pointed out, but its shell programming examples really help me. Those examples I can't find from other books. 2. This book will not help you too much in unix concepts, and thus you may have to buy another good unix concepts book to solve those problems. 3. overall, as long as you have enough time to play those examples in your unix machine and want to write a 30 pages of codes like those in chapter 21 and 22, this is definitely the one you want and bring you to another level! 4. personally, I buy two different books to study a computer skill. One is the text book by college professor who may insure the concepts are correct, the other is the book having enterprise examples. But it is so hard for one to find the one having both. This book partially fit my second need!

I own no less than ten books on shell programming and this one has helped me more than the rest combined. The author has the talent for condescending to my level to explain concepts that I have had a great deal of trouble understanding. I was able to write a menu driven script to simplify the loading and unloading of a tape library after reading just two chapters from the middle of the book. I even created my first shell function in the process. Yes there are a few typos. I'm not sure why some of the more sophisticated reviewers had a problem with this. I still found the book very useful and was able to catch the intended meaning in spite of the typos. If you are a genius this book may not be for you. If you are trying to learn how to write scripts quickly I highly recommend it. I would have traded all my other scripting books for this one had I known how useful it is.
