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.
-- Terminate option list.

meaning.
