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 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'') compliant.

HISTORY

     The mkfifo command appeared in 4.4BSD.
