MKNOD(8)		 BSD System Manager's Manual		      MKNOD(8)

NAME
     mknod - build special file

SYNOPSIS
     mknod [-m mode] name [b | c] major minor
     mknod [-m mode] name p

DESCRIPTION
     The mknod command creates device special files. Normally the shell script
     /dev/MAKEDEV is used to create special files for commonly known devices;
     it executes mknod with the appropriate arguments and can make all the
     files required for the device.

     The options are as follows:

     -m mode
	     Set the file mode. mode may be absolute or symbolic, as described
	     in chmod(1). In symbolic mode strings, the '+' and '-' operators
	     are interpreted relative to an assumed initial mode of "a=rw".

     To make nodes manually, the arguments are:

     name    Device or FIFO name. For example "sd" for a SCSI disk or a "pty"
	     for pseudo-devices. FIFOs may be named arbitrarily by the user.

     b | c | p
	     Type of device or FIFO. If the device is a block type device such
	     as a tape or disk drive which needs both cooked and raw special
	     files, the type is b. All other devices are character type dev-
	     ices, such as terminal and pseudo devices, and are type c. A FIFO
	     (also known as a named pipe) is type p.

     major   The major device number is an integer number which tells the ker-
	     nel which device driver entry point to use. To learn what major
	     device number to use for a particular device, check the file
	     /dev/MAKEDEV to see if the device is known.

     minor   The minor device number tells the kernel which subunit the node
	     corresponds to on the device; for example, a subunit may be a
	     filesystem partition or a tty line.

	     Major and minor device numbers can be given in any format accept-
	     able to strtoul(3), so that a leading "0x" indicates a hexade-
	     cimal number, and a leading "0" will cause the number to be in-
	     terpreted as octal.
