Unix shells by example

Until now, if you wanted to learn UNIX shell programming, you had to purchase three or four books, each covering just some of what you need to know. Now, one book is all you need: UNIX Shells by Example.

This is the first complete, step-by-step guide to using all three of the most important UNIX shells: the C shell, the Bourne shell, and the Korn shell; and the essential UNIX shell programming utilities. Using easy-to-understand, classroom-proven examples, it brings together all the information shell programmers need.

You'll start with the basics: what a UNIX shell is, what it does, and how it relates to other UNIX utilities and UNIX processes. You'll be introduced to shell scripts: what they do, and how to create and run them. There's detailed coverage of the essential tools every shell programmer should understand,including :

• Grep, Egrep and Fgrep.
• Sed, the Streamlined Editor
• Awk, the UNIX pattern scanning, text filter and report language.

Next, take a closer look at each of the three leading UNIX shells: the C shell, the Bourne shell, and the Korn shell. UNIX Shells by Example presents parallel coverage of each shell, so it's easy to see how they compare and when to use each.

Teachers and consultants will appreciate the Appendix that includes a listing of syntax and examples of many useful UNIX utilities, a comparison chart of all three shells, a complete guide to proper quoting, and classroom exercises for each topic.

The book's accompanying CD-ROM contains all example programs, a library of additional source code, and a suite of shell programming utilities for UNIX, Linux, DOS, Windows, OS/2, and Amiga systems.

Whether you're a system administrator, application developer or power user, UNIX Shells by Example is the most convenient, cost-effective way to learn UNIX shell programming.
