Summary:
This book is a self-paced tutorial based entirely on short, focused examples that demonstrate central concepts and effective programming techniques, with the newest version of KornShell, KSH93. It also provides coverage of such significant developments as CGI programming with KornShell, and offers an in-depth look at KornShell string handling. Taking a lighthearted, tongue-in-cheek approach, the book lightens the task of learning all the KornShell essentials; highlighted "Beware" sections warn you of potential pitfalls and keep you on track. The accompanying CD-ROM contains the U/WIN package of popular Unix utilities for Windowsr 95/98/NT, KSH93 binaries, the Apache web server, and the examples from the book.
