If that was the case, then that would be bug in the POSIX specification. I can't find a single printf implementations where printf -- outputs -- (I tried bash, zsh, ksh93, GNU, yash, busybox, busybox ash, Solaris /bin/printf). Even if POSIX didn't mandate printf -- -%s x to output -x, I'd say it would be a bug in the POSIX specification (it looks like it is). -- Stephane
