The Power of the Command Line - How Bash Can Boost Your Productivity - Werner Fischer, Thomas-Krenn.AG

Most Linux users use it every day: the bash shell. While Linux newbies only sporadically access the command line (terminal), their familiarity with it increases with continued use.

However, very few people take advantage of the sheer power of the bash. A basic understanding of the Bash grammar will help you get started: from simple commands, pipelines (|), lists, to compound commands, coprocesses, shell function definitions.

The Bash is incredibly versatile.

Quoting, for example, is used to remove the special meaning of certain characters or words to the shell. Values can be stored in parameters - of which there are several: positional parameters, special parameters, shell variables (e.g. $BASH, $LANG, $PATH, ...), arrays. Functions, arithmetic evaluation, conditional expressions and exit status are features often used in Bash scripts. Last but not least, shell bulletin commands are also part of the bash feature list.
