Raguel - Cleaner Shell Scripting

Abstract:

Raguel : Cleaner Shell Scripting

Why mostly people avoid Shell Scripting?

• It's ugly, a mess to maintain and easy to miss out on all constructs.

• In almost every implementations, never tested.

Why still people sometimes depend on Shell Scripts?

• For initial system bootstrap in case awesome PXE style is not to support.

• For general small system tasks where a full configuration management suite seems overkill.

For example, if I keep spawning new Virtual Machines often and my requirement is to get a specific package upgraded on it and grab output of some commands to confirm correct behavior.

Would I be interested in getting a powerful multi-featured config. management suite to first install, get setup and then perform all this. Or if just a "trustworthy clean maintainable" shell script can perform this minor task quickly, would I select that path.

If the answer is latter, here will be a quick demo of how. And also how to have tests for that too.
