NAME
mkdir − make a directory
SYNOPSIS
mkdir dirname ...
DESCRIPTION
Mkdir creates the specified directories; the directories are assigned the default access mode, which is determined by the umask(2) file creation mode mask. Standard entries, ‘.’, for the directory itself, and ‘..’ for its parent, are made automatically.
Mkdir requires write permission in the parent directory.
