POSIX printf doesn't currently specify any option, but still allows option processing. printf -- foo is required to output foo. printf -r foo is currently unspecified. Several printf implementations support some options (bash's, zsh's (not -r note, I was talking of print -f above), ksh93's, GNU's...). So I don't think there's anything preventing POSIX to specify a new option for printf. -- Stephane
