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. OPTIONS -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 directory exists. Create 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.
