Synopsis

Shell programs are the programs that are used as the interface between the user and the heart of the UNIX operating system, called the "kernel." The automation of shell tasks can be accomplished by more sophisticated UNIX programmers through the use of script files. This work introduces readers to the three major Unix shells (the Bourne, the C, and the Korn shells); the Linux shells (Bash and TC shells) and discusses tools, regular expressions, and quoting rules. The CD-ROM contains script files and datafiles used in the text. The use of small examples, which include the output and explanations of each line of programming, illustrate each concept.

About this title

Review

The second edition of Unix Shells by Examples shows off basic commands and utilities in the three most popular Unix shells--C, Bourne, and Korn--with side-by-side examples. The new edition of this book is sure to be a worthy reference for Unix programmers for getting around their favorite shell.

The best thing in this new edition is that the author presents short, effective examples of using basic commands and utilities for each of the three major Unix shells. This comparative approach means that you can use this book on different flavors of Unix and even migrate scripts between different shells. For each shell, the author provides fundamentals, like accessing profiles, command-line histories, and shell programming. "Lab sections" let you develop your skills with short, hands-on exercises for each shell. As in the earlier edition, the author's short examples show you how to perform basic tasks quickly with common switches and options.

Other sections here cover three major Unix utilities: grep (for searching), sed (for editing), and awk (for scripting and reporting). (The reference and tutorial on AWK programming is a notable feature here. There is also good coverage of regular expressions.)

Instead of hunting down information in countless man pages, this book will save you valuable time every day with its efficient format and comparative approach--truly useful features for the beginning and intermediate Unix user. --Richard Dragan

Topics covered: C, Bourne, and Korn Unix shells; grep, sed, and awk utilities; regular expressions; and shell programming.

From the Publisher

The best-selling Unix Shells by Example continues to be the only book you need to learn Unix shell programming. Unix Shells by Example, Third Edition adds thorough coverage of the new bash and tcsh shells to the full explanations in Quigley's famous treatment of the C, Bourne, and Korn shells and the awk, sed, and grep utilities, making this the most complete Unix shell programming book available anywhere.

Using proven techniques drawn from her acclaimed Silicon Valley Unix classes, Quigley transforms you into an expert-level shell programmer. You'll learn what the shells are, what they do, and how to program them, as well as how and when to use awk, sed, and grep. Code examples, completely revised and classroom-tested for this edition, explain concepts first-hand and can serve as the basis for your own projects.
