MODE is a mode for the new directory(s); see chmod(1).
GROUP and OWNER are the group and owner; see chown(1) and chgrp(1).

The --no-create option means don't do anything, print the commands instead.

If not specified on the command line, the environment variables MODE,
GROUP and OWNER are used.  If there are no environment variables, the
defaults used by mkdir(1) apply.
