Here's why --help and --version didn't work - you are using the bash
builtin, rather than coreutils' printf.  Try '/bin/printf --help' instead.

That's bash's error message.  Coreutils' is slightly more informative:
$ /bin/printf %02d 08
/bin/printf: 08: value not completely converted
00

The leading 0 means you are using an octal number, but 8 is not a valid
octal digit, hence the parsing stops after '0' leaving '8' unparsed.

Don't work too hard, make some time for fun as well!
