Synopsis

mkdir [options] directories

mkdir creates one or more directories:

$ mkdir directory1 directory2 directory3

Useful options

-p	Given a directory path (not just a simple directory name), create any necessary parent directories automatically: mkdir -p /one/two/three creates /one and /one/two if they don’t already exist, then /one/two/three.
-m mode	Create the directory with the given permissions: $ mkdir -m 0755 mydir By default, your shell’s umask controls the permissions. See the chmod command in File Properties, and File Protections.
