+.Nd build special file
+.Sh SYNOPSIS
+.Nm mknod
+.Ar name
+.Op Cm c | Cm b
+.Ar major minor
+.Sh DESCRIPTION
+The
+.Nm mknod
+command creates device special files.
+Normally the shell script
+.Pa /dev/MAKEDEV
+is used to create special files for commonly known devices; it executes
+.Nm mknod
+with the appropriate arguments and can make all the files required for the
+device.
+.Pp
+To make nodes manually, the four required arguments are:
+.Pp
+.Bl -tag -width majorx
+.It Ar name
+Device name, for example
+.Dq sd
+for a SCSI disk on an HP300 or a
+.Dq pty
+for pseudo-devices.
+.It Cm b | Cm c
+Type of device. 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
+.Cm b .
+All other devices are character type devices, such as terminal
+and psuedo devices, and are type
+.Cm c .
+.It Ar major
+The major device number is an integer number which tells the kernel
+which device driver entry point to use.  To learn what
+major device number to use for a particular device, check the file
+.Pa /dev/MAKEDEV
+to see if the device is known, or check
+the system dependent device configuration file:
+.Bd -filled -offset indent
+.Dq Pa /usr/src/sys/conf/device. Ns Em architecture
+.Ed
+.Pp
+(for example
+.Pa device.hp300 ) .
+.It Ar 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.
