Unix Shells by Example

The first book that covers all three UNIX shells plus awk, sed, and grep! One book is all you need to learn UNIX shell programming! UNIX Shells by Example is your complete, step-by-step guide to three essential UNIX shells-C, Bourne, and Korn-and three essential UNIX shell programming utilities-awk, sed, and grep. This new Second Edition is better than ever, with even more classroom-proven examples from Silicon Valley's top UNIX instructor, Ellie Quigley! Starting with the basics, Quigley gets you all the way to expert-level techniques. Along the way, you'll master all this and more: • UNIX shells: what they are, what they do, how they integrate with other UNIX utilities and processes • Creating, running, and debugging shell scripts • Using grep, egrep, and fgrep • Working with sed, the Streamlined Editor • Completely updated awk coverage: pattern scanning, text filtering, reporting, and much more! Quigley presents parallel coverage of all three shells, so it's easy to see how they compare-and when to use each. You'll find hands-on exercises for every topic, an appendix with detailed syntax listings, examples of many useful UNIX utilities, comparison charts, and much more. Whether you're a system administrator, application developer, or power user, UNIX Shells by Example, Second Edition, is the most convenient, cost-effective way to learn UNIX shell programming.
