Permissions to use when creating the directory (defaults to 0o777, before the process's umask). Ignored on Windows.

Defaults to false. If set to true, means that any intermediate directories will also be created (as with the shell command mkdir -p). Intermediate directories are created with the same permissions. When recursive is set to true, succeeds silently (without changing any permissions) if a directory already exists at the path, or if the path is a symlink to an existing directory.
