Product Review
In both Linux and Unix, becoming proficient at using shell scripts is an essential skill for both programmers and administrators. Filled with numerous exercises and examples, Ellie Quigley's Linux Shells by Example provides a comprehensive tutorial to two of the most popular Linux shells: the Bourne Again shell (bash) and the TC shell (tcsh). For any Linux user, this title is all you need to bring your shell-programming skills up to speed.
This book opens with a tour of the history and function of traditional Unix shells (from Bourne, C, and Korn shells) before centering on Linux variants, bash and tcsh. The text then turns to three powerful utilities: grep (for file searching), sed (for noninteractive file editing), and gawk (which allows programmers to write powerful scripts that process files using regular expressions).
There are dozens of sample commands to try out here. (With shell programming, the genius is truly in the details, and the only way to learn the shell is to try it out for yourself.) As an experienced teacher, the author provides a wealth of examples that take you through both the common and more esoteric features of these utilities. Instead of hard-to-decipher man pages, there she includes dozens of sample commands with correct syntax, plus clear explanations.
The rest of this book looks at the bash and tcsh shells in detail, from interactive mode to shell programming with full coverage of the basics of writing reusable scripts. Final sections of Linux Shells by Example look at common Linux file and system commands for easy reference, and the book ends with a useful appendix on quoting styles for five different shells. In all, this book's clear presentation style and plentiful examples will help any Linux user become a competent shell user and script programmer. --Richard Dragan

Customer Reviews & Comments
I just started this book but have thumbed through all the chapters. The author is a very good writer and seems to be passionate about the subject unlike some of the authors that write dry tombs for O'Reilly. However, "Unix Power Tools", O'Reilly is not a dry tomb. Anyway, better know your way around linux before you get this book even though it starts very basic. This is a huge book, 761 pages. Great info...
