Description
This tutorial is to help people understand some of the basics of shell
script programming (aka shell scripting), and hopefully to introduce some of the possibilities of simple but
powerful programming available under the Bourne shell. As such, it has been written as
a basis for one-on-one or group tutorials and exercises, and as a reference for subsequent
use.

This tutorial assumes some prior experience; namely:

Use of an interactive Unix/Linux shell
Minimal programming knowledge - use of variables, functions, is useful background knowledge
Understanding of some Unix/Linux commands, and competence in using some of the more common ones. (ls, cp, echo, etc)
Programmers of ruby, perl, python, C, Pascal, or any programming language (even BASIC) who can maybe read shell scripts, but don't feel they understand exactly how they work.
