MKFIFO(1)		  BSD General Commands Manual		     MKFIFO(1)

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 speci-
	     fied 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	sym-
	     bols "+" (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 modi-
     fied by the umask(2) of the calling process.  The mkfifo utility requires
     write permission in the parent directory.

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

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

STANDARDS
     The mkfifo	utility	is expected to be IEEE Std 1003.2 ("POSIX.2") compli-
     ant.

HISTORY
     The mkfifo	command	appeared in 4.4BSD.
