Hello,

there is an error at the end of the example:

  printf "Remaining arguments are: %s\n$*"

should be

  printf "Remaining arguments are: %s\n" "$*"

(cf.
https://pubs.opengroup.org/onlinepubs/9699919799/utilities/getopts.html )

I would have sent a patch, but couldn't find the POSIX man page sources.
Are they available somewhere?

  Thanks,

  Štěpán
