NAME
      mkdir - make directories
 


SYNOPSIS
      mkdir [ -m mode ]  [ -p ]  dir ...
 


DESCRIPTION
      The mkdir command creates the named directories in mode  777
      (possibly altered by the file mode creation mask umask(1)).
 
      Standard entries in a directory  (for  instance,  the  files
      ".", for the directory itself, and "..", for its parent) are
      made automatically. mkdir cannot  create  these  entries  by
      name.  Creation  of a directory requires write permission in
      the parent directory.
 
      The owner-ID and group-ID of the new directories are set  to
      the  process's effective user-ID and group-ID, respectively.
      mkdir calls the mkdir(2) system call.
 
   setgid and mkdir
      To change the setgid bit on a newly created  directory,  you
      must use chmod g+s or chmod g-s after executing mkdir.
 
      The setgid bit setting is inherited from the  parent  direc-
      tory.
 


OPTIONS
      The following options are supported:
 
           -m mode
                 This option allows users to specify the  mode  to
                 be  used  for  new directories. Choices for modes
                 can be found in chmod(1).
 
           -p    With this option, mkdir creates dir  by  creating
                 all  the  non-existing  parent directories first.
                 The mode given to intermediate  directories  will
                 be the difference between 777 and the bits set in
                 the file mode creation mask. The difference, how-
                 ever,  must  be  at  least 300 (write and execute
                 permission for the user).
 
 


OPERANDS
      The following operand is supported:
 
      dir   A path name of a directory to be created.
 
 USAGE

      LC_MESSAGES, and NLSPATH.
 
 EXIT STATUS
      The following exit values are returned:
 
      0     All the specified directories  were  created  success-
            fully  or  the  -p  option  was  specified and all the
