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; and 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.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.
