mkdir(1)                         User Commands                        mkdir(1)

NAME
       mkdir - make directories

SYNOPSIS
       /usr/bin/mkdir [-m mode | --mode=mode] [-p | --parents]
            [-v | --verbose] [--help] 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  re‐
       quires 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 directory.

OPTIONS
       The following options are supported:

       --help                  Display usage message and exit.


       -m mode, --mode=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, --parents           With this option, mkdir creates dir by creating
                               all the non-existing parent directories  first.
                               The  mode  given to intermediate directories is
                               the difference between 777 and the bits set  in
                               the  file  mode  creation mask. The difference,
                               however, must be at least 300 (write  and  exe‐
                               cute permission for the user).


       -v, --verbose           Display  a  summary message for the created di‐
                               rectory or directories.


OPERANDS

       dir    A path name of a directory to be created.
