The HP-UX one is actually OK with that. The error is from an old gnu coreutils (2.0), and it's complaining because there no leading zero, which POSIX says octal escapes have: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/printf.html

""" The following <backslash>-escape sequences shall be supported: [...] "\0ddd", where ddd is a zero, one, two, or three-digit octal number that shall be converted to a byte with the numeric value specified by the octal number """

$ /usr/local/bin/printf '\03' | od -x 0000000 0300 0000001 $ /usr/local/bin/printf '\3' | od -x /usr/local/bin/printf: \3: invalid escape 0000000

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
