Description:
The Advanced Bash-Scripting Guide
An in-depth exploration of the art of shell scripting. . This tutorial assumes no previous knowledge of scripting or programming, but progresses rapidly toward an intermediate/advanced level of instruction ... all the while sneaking in little snippets of UNIX(R) wisdom and lore. It serves as a textbook, a manual for self-study, and a reference and source of knowledge on shell scripting techniques. The exercises and heavily-commented examples invite active reader participation, under the premise that the only way to really learn scripting is to write scripts. . This book is suitable for classroom use as a general introduction to programming concepts.
