That "stat -c" is a GNU-ism, I think.  macOS CI jobs at GitHub do
not seem to like it.

Also, please see Documentation/CodingGuidelines to learn the subset

Sorry, forgot to say that if you are merely interested to react to
the fact that a file has non-empty contents,

	if test -s "$2"
	then
		... file $2 is not empty ...
	fi &&
	...

should be a way to do so.

Thanks.
