 Learning the Korn Shell (2nd Edition)
This book is excellent for beginner-intermediate users. I did not have any experience with Unix scripts prior to this book, after finishing it I came away with a very good understanding of the Korn Shell.
br /
br /Book is well written and covers the basics: command line editing, setting up your environment, up to process handling and debugging. One flaw of the book is that there is not enough examples. Also many of the examples later on in the book are built based on examples from previous chapters. While that is good for a learning exercise it does not give you a direct, simple example you may require.
br /
br /Overall I would definitely recommend this book, I still use this as a reference at work.
 Good Book, Worth Buying
I bought this book a few days ago for use at work. Previously, I didn't have much of a need for interacting with a Unix shell outside of cd and ls.
br /
br /This book reads easy, and the author(s) seem genuinely interested in the subject - not the usual dry textbook point of view. Topics are explained well, with small examples to show how it actually works. I would suggest having access to a Unix machine with the Korn shell, as you can experiment with the commands a bit on your own.
br /
br /BTW, I didn't realize that the Unix machine I work on has the 1988 version of the Korn shell instead of the 93 version (the book covers 93), but most of the book is still relevant. They also cover what has changed in the 2 versions.
Learning the Korn Shell (2nd Edition)
I once was blind. Spending decades in the UNIX world I spent time with several shells. Down through the years I visited many shells and even bought a book on the Korn Shell by the designer David Korn. I sort of got complacent (know-it-all).
br /
br /Now obtaining a position supporting AIX I once again find that the prefer supported shell is the Korn shell; even sh is linked to ksh93. Several times I came across unexplainable anomalies; sometime paths would be absolute and at other times they would follow links. Traps seemed to work a tad different and other outcomes seemed to be hit or miss.
br /
br /The purchase of this book has been a real eye opener. What seemed to be arbitrary was in reality lack of personal knowledge of the latest version of the korn shell.
br /
br /I could not believe that a book by David Korn of ATT did not even mention signals.
br /
br /Some of the highlights of the book are:
br /Job control
br /Functions
br /Command history
br /Command-line editing
br /Integrated programming features
br /Control structures
br /Debugging primitives
br /Regular expressions
br /Advanced I/O features
br /New options and variables
br /Increased speed
br /Security features
br /Major features
br /Security features
br /POSIX compliance
br /Arithmetic for loops
br /Floating-point arithmetic
br /Structured variable names
br /Indirect variable references
br /Associative arrays
br /Additional text manipulation facilities
br /More built-in commands

Excellent
This book is just great. It has a lot of examples and every concept is well explained. Even for those who are not used to programming, this is a great book to start shell scripting.
br /The authors relate concepts (commands usage, for example) with those of bash and other shells, which is very helpful if you already know how to program with csh, Bourne, etc.
br /So... if you're looking for a GOOD book about ksh, buy this one!!
Very Helpful Reference to KSH
I found this book very helpful in learning to write scripts for the Korn Shell. I keep it on my desk all the time now, even for other shells (Bash/etc). It's an invaluable reference to me.
