MKFIFO(1L)

NAME
mkfifo - make FIFOs (named pipes)

SYNOPSIS
mkfifo [-m mode] [--mode=mode] path...

DESCRIPTION
This manual page documents the GNU version of mkfifo. mkfifo creates a FIFO with each given name. By default, the mode of created FIFOs is 0666 minus the bits set in the umask.

  OPTIONS

-m, --mode mode
    Set the mode of created FIFOs to mode, which is symbolic as in chmod and uses the default mode as the point of departure.

The long-named options can be introduced with `+' as well as `--', for compatibility with previous releases. Eventually support for `+' will be removed, because it is incompatible with the POSIX.2 standard.
