MKDIR(1)                   OpenBSD Reference Manual                   MKDIR(1)

NAME
     mkdir - make directories

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

DESCRIPTION
     The mkdir utility 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 mode
             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) utility.  If a symbolic mode is
             specified, the operators `+' and `-' are interpreted 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.  Do not consider it an error
             if the argument directory already exists.

     The user must have write permission in the parent directory.

     The mkdir utility exits 0 on success or >0 if an error occurred.

EXAMPLES
     mkdir foobar

     Create a directory named foobar.

     mkdir -m 700 foobar

     Create a directory named foobar and set its file mode to 700.

     mkdir -p cow/horse/monkey

     Create a directory named cow/horse/monkey, creating any non-existent in-
     termediate directories as necessary.

SEE ALSO
     chmod(1), rmdir(1), umask(2)

STANDARDS
     The mkdir utility is expected to be IEEE Std1003.2 (``POSIX.2'') compati-
     ble.

HISTORY
     A mkdir command appeared in Version 1 AT&T UNIX.
