Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Hi all, this request essentially illustrates my weakness with shell scripts. I have a script that reads in a string that will be in CamelCase and I want to convert the value into first lowercase and then uppercase with an underscore inserted at each Capital letter, after the first appearance, hence:
I'm sure that there is an easy way to do this in bash, but I need someone to help me find it, many thanks.
You're right! Folding case is in the latest bash as documented here (scroll down to the last expansions). IDK which version it's in, maybe 4+?
It is indeed a 4.x feature, however it's not useful for going from TestCaseVariable to test_case_variable. The problem is in inserting the _ properly. It is, however, useful for going from test_case_variable to TEST_CASE_VARIABLE.
