| Unfortunately that advice is not true without further caveats.
That you have to actually write a valid printf(1) command, and not
simply s/echo/printf/ ? Does that really need saying?
| netbsd$ sh -c "printf '-V\n'"
printf -- -V\\n
and it will work anywhere - our printf is specially hacked as once
upon a time it took no options, and this kind of thing would work.
Format strings starting with a '-' don't work in general however,
the '--' should be included if the format might begin with a '-'.
Even better would be
printf -- %s\\n -V
(where the -- is optional here).
kre
aside: I'd use '-V\n' inside "" as well. But as a sh -c command
string I'd use:
sh -c 'printf -- -V\\n'
