system. It shows them how to take control of their systems and work efficiently
by harnessing the power of the shell to solve common problems. The reader learns

Bourne shell, such as bash. Three are covered in the third edition of Unix
Shell Programming. It begins with a generalized tutorial of Unix and tools
and then moves into detailed coverage of shell programming.
Topics covered include: regular expressions, the kernel and the utilities,

the shell.

No other scripting book as clear and definitive as this text.
Kochan and Woods have supplied us with a pedagogically exellent text on Bourne Shell scripting. It is exceptionally clear and provides good examples. The wording is at a level that almost everyone can understand. The concepts are clear and simply illustrated. Many intermediate commands are clearly explained.
After reading this it left me wishing that they had authored an "introduction to Unix" text. Most of my (Toronto, Canada) third term students (who had to use this text for our scripting course) wished that we could have used it for the (second term) introductory Unix course. However, it is missing some fundamentals (which is reasonable since it focuses on the shell, and not the entire system).
This text has been around for over 15 years, and no other text written before, or after, comes close to its value. Its a "must buy" if you want to understand anything about scripting.
Even SCO (in Canada) must think highly of this text as they have (in the past) included a copy with their own SCO scripting course (as delivered by triOS) materials.

Great book on shell programming
This is the book to have for shell programming. Detailed yet succinct. It's much better than "Unix in a nutshell"
