Pro Bash Programming
teaches you how to effectively utilize the Bash shell
in your programming. The Bash shell
is a complete programming language, not merely a glue to combine external Linux commands. By taking full advantage of Shell internals, Shell programs can perform as snappily as utilities written in C or other compiled languages. And you will see how, without assuming Unix lore, you can write professional Bash
4.3 programs through standard programming techniques.
This second edition has updated for Bash
4.3, and many scripts have been rewritten to make them more idiomatically Bash, taking better advantage of features specific to Bash. It is easy to read, understand, and will teach you how to get to grips with Bash
programming without drowning you in pages and pages of syntax.
