7.3 mkfifo: Make FIFOs (named pipes)

mkfifo creates FIFOs (also called named pipes) with the specified names. Synopsis:

mkfifo [option] name...

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.

The program accepts the following option. Also see 2. Common options.

`-m mode'

`--mode=mode'

Set the mode of created FIFOs to mode, which is symbolic as in chmod and uses `a=rw' (read and write allowed for everyone) minus the bits set in the umask for the point of departure. See section 3. File permissions.
