Product Description
It's simple: you need to know how to work with the bash shell if you want to get to the heart of Mac OS X, Linux, and other Unix systems. Updated for the most recent version of bash, this concise little book puts all of the essential information about bash at your fingertips. You'll quickly find answers to annoying questions that always come up when you're writing shell scripts -- What characters do you need to quote? How do you get variable substitution to do exactly what you want? How do you use arrays? -- and much more.
If you're a user or programmer of any Unix variant, or if you're using bash on Windows, you'll find this pocket reference indispensable. This book covers:
- Invoking the Shell
- Syntax
- Functions
- Variables
- Arithmetic Expressions
- Command History
- Programmable Completion
- Job Control
- Shell Options
- Command Execution
- Coprocesses
- Restricted Shells
- Built-in Commands

If you are new to this 'shell' business, I would recommend Linux Pocket Guide (Pocket Guide: Essential Commands) for a first text - it is less advanced, very well explained and slightly cheaper. More of a BASH tutorial than a reference.
If you are moving to Linux (and why not, with all the free software and industrial-strength defences against malware?) then it would be good if someone in the family understands how BASH works.
If (like me) you already have the Linux Pocket guide, then this is an ideal adjunct to it - with more and deeper detailed descriptions, less tutorial content. My UNIX involvement started in the early 1980s, but I still find both these nifty pocket books very useful indeed, and interesting to read, too.
Probably not the ideal introduction to BASH, but a perfect companion to a BASH tutorial and a super reference for day-to-day use.
Recommended!
