I do a fair amount of scripting and automation with bash (our default shell on Solus and many other Linux distributions).
I've compiled and revised a bunch of battle-tested bash functions and "bash·isms" into modules that can be separately loaded as needed. (As of now, there are 103.)
Check them out here if you're interested:

Manual of functions
(These were all developed on Solus, but will work on any bash (4.0+) shell running Linux.)
Hope some other heavy bash users can find these useful.
