NAME

     mkfifo -- make fifos

SYNOPSIS

     mkfifo [-m mode] fifo_name ...

DESCRIPTION

     mkfifo creates the fifos requested, in the order specified.  By default, the resulting fifos have mode 0666 (rw-rw-rw-), limited by the cur-
     rent umask(2).

     The options are as follows:

     -m      Set the file permission bits of newly-created fifos to mode, without respect to the current umask.

	     The mode is specified as in chmod(1).  In symbolic mode strings, the ``+'' and ``-'' operators are interpreted relative to an assumed
	     initial mode of ``a=rw''

     mkfifo requires write permission in the parent directory.

     mkfifo exits with 0 if successful, and with >0 if an error occurred.

LEGACY DESCRIPTION

     In legacy mode, the fifo's file permission bits are always limited by the current umask.

     For more information about legacy mode, see compat(5).
