It's actually more appropriate to install dash, and write the script with that.

When this is done, it will run in all the shells, because the script becomes POSIX-compliant.

Making a macOS-specific script which does not make sense to run anywhere else portable to other platforms is entirely a waste of time.

		Portability between bash and zsh is a waste of time? Wasn't a previous argument that legacy Macs should remain supported if possible? smh.
