-p, --parent Ensure that the given path(s) exist:

Parent dirs default to umask modified by `u+wx'.
Do not consider an argument directory that already
exists to be an error.
-m, --mode=mode Set the mode of created directories to `mode', which is
symbolic as in chmod and uses the umask as a point of
