NAME

     mkfifo - make FIFOs (named pipes)

SYNOPSIS

     mkfifo [options] file...

     POSIX options:  [-m mode]

     GNU options (shortest form):  [-m mode] [--help] [--version]
     [--]

DESCRIPTION

     mkfifo creates FIFOs (also called "named  pipes")  with  the
     specified filenames.

     A "FIFO" is a special file  type  that  permits  independent
     processes  to  communicate.  One process opens the FIFO file
     for writing, and another for reading, after which  data  can
     flow  as  with  the  usual anonymous pipe in shells or else-
     where.

     By default, the mode of created FIFOs is 0666 (`a+rw') minus
     the bits set in the umask.

OPTIONS

     -m mode, --mode=mode
          Set the mode of created FIFOs to mode,  which  is  sym-
          bolic  as  in chmod(1) and uses the default mode as the
          point of departure.

GNU STANDARD OPTIONS

     --help
          Print a usage message on standard output and exit  suc-
          cessfully.

     --version
          Print version information on standard output, then exit
          successfully.

     --   Terminate option list.

ENVIRONMENT

     The variables LANG, LC_ALL, LC_CTYPE  and  LC_MESSAGES  have
     the usual meaning.
