The subdirectory message is being sent to STDERR by the 'md' command not Perl. I found this in the Perl documentation with regards to what $res is being assigned, The collected standard output of the command is returned; standard error is unaffected. In scalar context, it comes back as a single (potentially multi-line) string, or undef if the command failed.
