I have used the bash extension Oh-My-Bash now for a while and it is really useful and beginner friendly.

The name sounds familiar from the Oh-My-ZSH project and it is quite similar, just for #bash

Oh My Bash

Oh-My-Bash is an open source, community-driven framework for managing your BASH configuration. It comes bundled with a ton of helpful functions, helpers, plugins, themes, and a few things that make you shout... OH MY BASH!
