Summary: A good textbook-style reference for Korn
Review: When I bought this book, I had already spent a year working in a UNIX environment, but I had no real experience with shell programming. However, after reading this book, I'm having no problems writing intermediate to advanced level Korn scripts at work.It sounds like some people who have reviewed this were expecting a Nutshell book, but apparently they didn't read the description of the book. To truly appreciate this book, one should read it in a fairly linear fashion, from cover to cover (like a textbook). It's not really meant to be skimmed, since it's not one of the Nutshell books. Whatever the case, I think that for anyone interested in Korn shell programming, this is a pretty good introduction to it. My only recommendation is that you practice the concepts in the book while reading, and make sure you have a copy of 'UNIX in a Nutshell'.

Summary: Straight to the top!
Review: When I started my current position, I had little to no experience in scripting. After reading this book I have become the top scripter on our team. Now when tasks need to be automated, I've become the go-to-guy (not always good but at least it is a form of recognition). I have recommened this book to new memebers of my team. In fact, I think someone has my copy now. Hummm... who was it?

Summary: A must if you use KSH
Review: While not as popular (at least in Linux circles) as bash, ksh is a powerful language/tool. Put bluntly, this is one of the few O'Reilly books I have read cover to cover. That isn't to say that the others don't warrant a thorough perusal, but that this book was readily accessible and provided excellent information. I have used it as a reference countless times over the years and do not hesitate to recommend it to anyone using or considering using ksh. Moreover, if you are considering using ksh - or perhaps need a better background in Unix shell scripting - read this book.
