mkdir で複数階層のディレクトリ（例えば foo/bar/ など）を一気に作成したい場合は -p オプションを使う。
% mkdir -p foo/bar/manual page には次のように書かれている。
-p Create intermediate directories as required. If this option is not specified, the full path prefix of each operand must already exist. On
the other hand, with this option specified, no error will be reported if a directory given as an operand already exists. Intermediate
directories are created with permission bits of “rwxrwxrwx” (0777) as modified by the current umask, plus write and search permission for the
owner.参考
