MKDIR(1) BSD Reference Manual MKDIR(1)
mkdir - make directories
mkdir [-p] [-m mode] directory_name ...
Mkdir creates the directories named as operands, in the order specified,
using mode rwxrwxrwx (0777) as modified by the current umask(2).
The options are as follows:
-m Set the file permission bits of the final created directory to
the specified mode. The mode argument can be in any of the for-
mats specified to the chmod(1) command. If a symbolic mode is
specified, the operation characters ``+'' and ``-'' are inter-
preted relative to an initial mode of ``a=rwx''.
-p Create intermediate directories as required. If this option is
not specified, the full path prefix of each operand must already
exist. Intermediate directories are created with permission bits
of rwxrwxrwx (0777) as modified by the current umask, plus write
and search permission for the owner.
The user must have write permission in the parent directory.
Mkdir exits 0 if successful, and >0 if an error occurred.
The mkdir utility is expected to be IEEE Std1003.2 (``POSIX'') compati-
