NAME
     mkfifo -- make fifos

SYNOPSIS
     mkfifo [-m mode] fifo_name ...

DESCRIPTION
     The mkfifo utility creates the fifos requested, in the order specified.

     The options are as follows:

     -m      Set the file permission bits of the created fifos to the specified mode, ignoring
	     the umask(2) of the calling process.  The mode argument takes any format that can be
	     specified to the chmod(1) command.  If a symbolic mode is specified, the op symbols
	     ``+'' (plus) and ``-'' (hyphen) are interpreted relative to an assumed initial mode
	     of ``a=rw'' (read and write permissions for all).

     If the -m option is not specified, fifos are created with mode 0666 modified by the umask(2)
     of the calling process.  The mkfifo utility requires write permission in the parent direc-
     tory.

DIAGNOSTICS
     The mkfifo utility exits 0 on success, and >0 if an error occurs.

STANDARDS
     The mkfifo utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compliant.

SEE ALSO
     mkdir(1), rm(1), mkfifo(2), mknod(2), mknod(8)
