Sure, but just trying to write portable code is not beyond acceptable
means of preventing stupid things from happening.

I'm afraid I have to use shell here.


If someone has an idea whether my assumption about built-in printf is
correct, i.e. that it would be safe, and whether the method with
command -v is safe to check for that I'd still be interested to hear,
of course also if someone knows some nice other way.
