NAME    [Toc]    [Back]

     mknod - build special file	or named pipe (FIFO)

SYNOPSIS    [Toc]    [Back]

     mknod name	b | c major minor
     mknod name	p

DESCRIPTION    [Toc]    [Back]

     mknod makes a directory entry and corresponding inode for a special file
     or	named pipe.  The first argument	is the name of the entry to create.

     In	the first form of the command, the second argument is b	if the special
     file describes a block device (disks, tape) or c if it is a character
     device (for example, a tty	line).	The last two arguments are numbers
     specifying	the major device number	and the	minor device number (for
     example, the unit,	drive, or line number).	 They may be either decimal or
     octal.  The assignment of major device numbers is specific	to each
     system.  The information is contained in the system source	file
     /usr/include/sys/major.h.

     You must be the superuser to use this form	of the command.	 The normal
     convention	is to keep all special device files under the /dev directory.

     The second	form of	the mknod command is used to create named pipes
     (a.k.a. FIFOs).  This form	of the command is not restricted to the
     superuser.
