file systems

I have been teaching UNIX for over 15 years. I have used many introductory books but this is by far the best. The authors seem gifted with the ability to explain difficult topics with ease.

Some of the salient features of the book that I particularly like are:
a. Topics are arranged in a very nice, ascending order of difficulty
b. The book is very comprehensive and I often use it
c. The book discusses important OS concepts not found in any other introductory book on UNIX
d. Shell scripting is explained very well and, unlike many other books in programming, ALL of the programs in the book actually work!
e. Nice intorductory chapter on X Window System

I look forward to more introductory books on computer science by the author team.

This book will waste your time. The author can't explain basic staff.

Not even one script worked!! Here is exactly in the book on page 417:" We do not show the program headers...for the sake of saving space." If I can get it myself, why should I read your book?! There are a lots of similar non-sense stuff!

If you want to have headache, then buy this book. I will never buy any book from this author anymore.

I wish other people had written this before I bought it.

This book is wonderful, it is a very usefull text/reference book. I never had any experience before with Unix. After reading this book, I found it to be very educational and entertaining. I give it two thumbs up. A++
