NAME
       mknod - create special files

SYNOPSIS
       name major minor

       name major minor

       name

DESCRIPTION
       The command creates the following types of files:

	      o	 Character device special file (first SYNOPSIS form),
	      o	 Block device special file (second SYNOPSIS form),
	      o	 FIFO  file,  sometimes	 called	 a  named pipe (third SYNOPSIS
		 form).

       name is the path	name of	the file to be	created.   The	newly  created
       file  has  a  default  mode  that is readable and writable by all users
       (0666), but the mode is modified	by the current setting of  the	user's
       file mode creation mask (see umask(1)).

   Character and Block Special Files
       Character  device  special files	are used for devices that can transfer
       single bytes at a time, such as nine-track magnetic tape	drives,	print-
       ers,  plotters, disk drives operating in	"raw" mode, and	terminals.  To
       create a	character special file,	use the	argument.

       Block device special files are used for devices that usually transfer a
       block of	data at	a time,	such as	disk drives.  To create	a block	device
       special file, use the argument.

       The remaining arguments specify the  device  that  will	be  accessible
       through the new special file:

	      major	     The  major	number specifies the major device type
			     (for example, the device driver number).

	      minor	     The minor number specifies	the  device  location,
			     which  is	typically,  but	 not always, the unit,
			     drive, and/or line	number.

       The major and minor values can each be specified	in hexadecimal,	octal,
       or decimal, using C language conventions	(decimal: no leading zero; oc-
       tal: leading zero; hexadecimal: leading

       The assignment of major and minor device	numbers	is  specific  to  each
       HP-UX  system.  Refer to	the System Administrator manuals supplied with
       your system for details.

       Only users who have appropriate privileges can use to create a  charac-
       ter or block device special file.

   FIFO	files
       To  create  a  FIFO (named pipe or buffer) file,	use the	argument.  You
       can also	use the	command	for this purpose (see mkfifo(1)).   All	 users
       can use to create FIFO files.

WARNINGS
   Access Control Lists
       In HFS file systems, optional ACL entries can be	added to special files
       and FIFOs with the command (see chacl(1)).  In JFS  file	 systems,  op-
       tional  ACL  entries  can  be added to special files and	FIFOs with the
       command (see  setacl(1)).   However,  system  programs  are  likely  to
       silently	change or eliminate the	optional ACL entries for these files.
