 12.3 `mkdir': Make directories
 ==============================
 
 `mkdir' creates directories with the specified names.  Synopsis:
 
      mkdir [OPTION]... NAME...
 
    `mkdir' creates each directory NAME in the order given.  It reports
 an error if NAME already exists, unless the `-p' option is given and
 NAME is a directory.
 
    The program accepts the following options.  Also see  Common
 options.
 
 `-m MODE'
 `--mode=MODE'
      Set the file permission bits of created directories to MODE, which
      uses the same syntax as in `chmod' and uses `a=rwx' (read, write
      and execute allowed for everyone) for the point of the departure.
       File permissions.
 
      Normally the directory has the desired file mode bits at the
      moment it is created.  As a GNU extension, MODE may also mention
      special mode bits, but in this case there may be a temporary window
      during which the directory exists but its special mode bits are
      incorrect.   Directory Setuid and Setgid, for how the
      set-user-ID and set-group-ID bits of directories are inherited
      unless overridden in this way.
 
      Note: The `--mode',`-m' option only applies to the right-most
      directories listed on the command line.  When combined with
      `--parents', `-p' option, any parent directories are created with
      `u+wx' modified by umask.
 
 `-p'
 `--parents'
      Make any missing parent directories for each argument, setting
      their file permission bits to the umask modified by `u+wx'.  Ignore
      existing parent directories, and do not change their file
      permission bits.
 
      To set the file permission bits of any newly-created parent
      directories to a value that includes `u+wx', you can set the umask
      before invoking `mkdir'.  For example, if the shell command
      `(umask u=rwx,go=rx; mkdir -p P/Q)' creates the parent `P' it sets
      the parent's permission bits to `u=rwx,go=rx'.  To set a parent's
      special mode bits as well, you can invoke `chmod' after `mkdir'.
       Directory Setuid and Setgid, for how the set-user-ID and
      set-group-ID bits of newly-created parent directories are
      inherited.
 
 `-v'
 `--verbose'
      Print a message for each created directory.  This is most useful
      with `--parents'.
 
 `-Z CONTEXT'
 `--context=CONTEXT'
      Set the default SELinux security context to be used for created
      directories.
 
 
    An exit status of zero indicates success, and a nonzero value
 indicates failure.
