Aside: zsh is standard on macs now, thanks to Apple's lawyers freaking out over bash license terms. If you want to change to industry standard bash (I did) then there are three ways to do it.

Short: csh -s /bin/bash

Others: system settings or terminal settings.

You may want to update bash via homebrew, or install the full set of Xcode command line tools. (But not full Xcode environment)

xcode-select --install
