mkdir



MKDIR(1)                    General Commands Manual                   MKDIR(1)


NAME

     mkdir - make directories


SYNOPSIS

     mkdir [-p] [-m mode] directory ...


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 newly created directory to
             mode.  The mode argument can be in any of the formats 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.  For an
     explanation of the directory hierarchy, see hier(7).


EXIT STATUS

     The mkdir utility exits 0 on success, and >0 if an error occurs.


EXAMPLES

     Create a directory named foobar:

           $ mkdir foobar

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

           $ mkdir -m 700 foobar

     Create a directory named cow/horse/monkey, creating any non-existent
     intermediate directories as necessary:

           $ mkdir -p cow/horse/monkey
