mkdir - make directories mkdir [-p] [-m mode] [--parents] [--mode=mode] [--help] [--version] dir... This manual page documents the GNU version of mkdir . mkdir creates a directory with each given name. By default, the mode of created directories is 0777 minus the bits set in the umask.

"-m, --mode mode" Set the mode of created directories to mode , which is symbolic as in chmod and uses the default mode as the point of departure.

"-p, --parents" Ensure that each given path exists. Make any missing parent directories for each argument. Parent directories default to the umask modified by `u+wx'. Do not consider an argument directory that already exists to be an error.

"--help" Print a usage message on standard output and exit successfully.

"--version" Print version information on standard output then exit successfully.
