Learning the Korn Shell, 2nd Edition
Publisher: O'Reilly Media
Final Release Date: April 2002
Pages: 434

The Korn shell is an interactive command and scripting language for accessing Unix® and other computer systems. As a complete and high-level programming language in itself, it's been a favorite since it was developed in the mid 1980s by David G. Korn at AT&T Bell Laboratories. Knowing how to use it is an essential skill for serious Unix users. Learning the Korn Shell shows you how to use the Korn shell as a user interface and as a programming environment.Writing applications is often easier and quicker with Korn than with other high-level languages. Because of this, the Korn shell is the most often used shell in commercial environments and among inexperienced users. There are two other widely used shells, the Bourne shell and the C shell. The Korn shell, or ksh, has the best features of both, plus many new features of its own. ksh can do much to enhance productivity and the quality of a user's work, both in interacting with the system, and in programming. The new version, ksh93, has the functionality of other scripting languages such as awk, icon, Perl, rexx, and tcl.Learning the Korn Shell is the key to gaining control of the Korn shell and becoming adept at using it as an interactive command and scripting language. Prior programming experience is not required in order to understand the chapters on basic shell programming. Readers will learn how to write many applications more easily and quickly than with other high-level languages. In addition, readers will also learn about Unix utilities and the way the Unix operating system works in general. The authors maintain that you shouldn't have to be an internals expert to use and program the shell effectively.The second edition covers all the features of the current version of the Korn shell, including many new features not in earlier versions of ksh93, making it the most up-to-date reference available on the Korn shell. It compares the current version of the Korn shell to several other Bourne-compatible shells, including several Unix emulation environments for MS-DOS and Windows. In addition, it describes how to download and build ksh93 from source code.A solid offering for many years, this newly revised title inherits a long tradition of trust among computer professionals who want to learn or refine an essential skill.

    Comments about oreilly Learning the Korn Shell, 2nd Edition:

    I picked up this book after a Korn shell scripting class to develop my skills a bit further, and it definitely paid off. This is a great book for learning the Korn shell as well as for reference, and it comes with a little folding quick reference guide to the shell that is a great help when you are writing scripts. I've had this book for about six months now, I refer to it constantly, and I highly recommend it.

    Comments about oreilly Learning the Korn Shell, 2nd Edition:

    I didn't really like this book. I've read through 4 chapters, and gave up. Too much theory, very few examples. Examples and explanations are very confusing. I wouldn't recommend this book as reference or as a study guide.
