mkfifo

Make FIFOs (named pipes) with the specified names.

Syntax
      mkfifo [options] NAME...

Options

 -m MODE
 --mode=MODE
      Set the mode of created FIFOs to MODE, which is symbolic as in
      `chmod' and uses 0666 (read and write allowed for everyone) minus
      the bits set in the umask for the point of departure.

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.

"Ceci n'est pas une pipe" (This is not a pipe) ~ Magritte
