don't assume bash is installed

On systems like OpenBSD bash isn't available by default, this removes the hard coded path.

Can anyone gander at this? It's pretty straight forward.

At the very least it should be "#!/usr/bin/env bash".

Not sure if you are the right reviewer for this, but hopefully you can point me
in the right direction.

This script is pretty simple.. but it breaks on systems that don't have bash
installed in /bin by default (OpenBSD for sure).
