`#!/bin/sh' makes this less portable than it could be, if /bin/sh doesn't exists on my system it won't work, for example. Remove that line and it'll work everywhere.

If /bin/sh does not exist, what in the world is executing the shell script?

The shell, of course. It just might not be (because it doesn't have to be) located in /bin.

I’m pretty sure that /bin/sh is mandated by POSIX.

It's not. See https://pubs.opengroup.org/onlinepubs/9799919799/utilities/s...

    Applications should note that the standard PATH to the shell cannot be assumed to be either /bin/sh or /usr/bin/sh, and should be determined by interrogation of the PATH returned by getconf PATH, ensuring that the returned pathname is an absolute pathname and not a shell built-in.
