Not OP. But zsh isn't bash, and I am not about relearn my shell-fu.

1. It works just like bash if you want.

2. Scripts with #!/bin/bash or #!/bin/sh run as expected — even with bashisms.

zsh is derived from bash and much of the syntax and behavior is identical.

Also there are plugins like https://github.com/chrissicool/zsh-bash
