多段階層のディレクトリを一度で作成する
To create a directory, specify the directory name as the argument of the "mkdir" command and execute it, but if you specify a directory that does not exist when specifying a directory over a multi-level hierarchy, an error will occur.In such a case, you can force a non-existent directory to be created and create a multi-level directory at once by executing with the option "-p".
