Recommended reading: Here are some books on bash and shell programming I recommend:

Learning The Bash Shell

Learning the Bash Shell, Second Edition By Cameron Newham and Bill Rosenblatt

This is another one of the great books from O'Riley. While this is not a really a book for absolute beginners, it is clearly written and fairly complete.

Unix Shell Programming

UNIX Shell Programming, Revised Edition By Stephen G. Kochan and Patrick H. Wood

This book is rather dated and does not cover bash specifically (it is focused on the generic Bourne shell "sh"), but this is a really good book on shell programming. I think the order of presentation is excellent. While this book does not cover bash, all the scripts will work since sh is a subset of bash.

The AWK Programming Language

The AWK Programming Language by Alfred Aho, Brian Kernighan, and Peter Weinberger

AWK is a programming language that is often inserted into shell scripts. The syntax of AWK is very similar to the C programming language in which Linux/Unix and its utilities are written. Learning AWK will make you familiar with concepts that appear in many other programs. This book, written by the orginal authors of the language, is probably the finest programming book I have ever read. Filled with examples and clear explanations, this book will give you a taste for the power of this useful language. Note that this book is skinny and expensive, but I think it's well worth it.


Where

Linux/Unix Shell Scripting Sites

Heiner's SHELLdorado

SHELLdorado is a shell scripting education site. It features tutorials on various scripting topics and a large collection of shell scripts and functions.

Awk By Example, Part 1
Awk By Example, Part 2

Bash/Awk By Example is a series of tutorials presented by IBM.

Advanced Bash Scripting HOWTO

The Advanced Bash Scripting HOWTO is a detailed look at bash shell programming. A thoughtful treatment with lots of examples and exercises. A good companion piece for the LinuxCommand.org tutorials. Part of the Linux Documentation Project.

Bash Prompt HOWTO

The Bash Prompt HOWTO is a surprisingly interesting discussion of all the things you can make the prompt do. From the Linux Documentation Project.

Hard Core Linux Sites

Linux From Scratch

The Linux From Scratch tutorial will step you through the process of building a complete Linux system from source code.

"From Power Up To Bash Prompt" HOWTO

The From Power Up To Bash Prompt HOWTO tutorial builds a bare system, in a similar way to the "Linux From Scratch" tutorial, but it focuses more on just installing a bootable system instead of a complete system.

Why

Why did I make this site?

I think that shell programming is one of the great joys of working on Unix systems in general, and on Linux in particular. Almost all Linux systems feature the Bourne Again Shell (bash) which is a very nice shell with all of the best features of previous Unix shells such as sh (the orginal Bourne shell), csh (the C shell), and ksh (the Korn shell).

Also, there seem to be a lot of resources for other Linux programming tools like Perl, Python, tcl/Tk, etc. but very few that deal with bash shell programming, so I decided that the world needed one.
