Best syntax reference for shells

I have little yellow sticky notes all through this book on the references I use the most. I recommend it to all my system administrator colleagues, and it's a must for newbies to understand what's going on with their shells.

She also has a Perl by Example book that works the same way.

Best practical shell programming book on the market.

     UNIX Shells is a great book for both novice and experienced programmer. For once, somebody has written a computer book that is down to earth, clear, and replete with examples. You don't have to wade through pages of punishing prose or be a guru to understand this book. Each line of code in the examples is concisely yet fully explained. There's no guessing as to why any of the hundreds of sample scripts work the way they do. If your goal is to learn shell programming quickly so you can put it to use at work, this is the book to get.

Very Helpful

     I just got the third exition this book, it is extremely helpful. There aren't many examples of shell scripts on the web and none on the system man pages so it's a wonderfull reference. The sed, awk, grep section is also very helpful. All this stuff in one place makes it a great reference.
I would recommend this book to any intermediate level computer science student who is begining to learn the unix system.
