Description:

This document is both a tutorial and a reference on shell scripting
with Bash. It assumes no previous knowledge of scripting or
programming, but progresses rapidly toward an intermediate/advanced
level of instruction. The exercises and heavily-commented examples
invite active reader participation. Still, it is a work in progress.
The intention is to add much supplementary material in future updates
to this document, as it evolves into a comprehensive book that matches
or surpasses any of the shell scripting manuals in print.
