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 elsewhere.
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 can be symbolic 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 successfully.
- --version
-

- --
-
Terminate option list.
ENVIRONMENT
The variables LANG, LC_ALL, LC_CTYPE and LC_MESSAGES have the
usual meaning.
