MAKEDEV(8) System Manager's Manual (i386) MAKEDEV(8)

MAKEDEVcreate system and device special files

MAKEDEV name ...

The shell script MAKEDEV, found in the /dev directory, is used to create various special files. See intro(4) for a more complete discussion of special files.

MAKEDEV takes any number of device names as arguments, where the names are the common abbreviation for the device or group of devices.

Where a device name is followed by a star ‘*’, the star must be replaced by a unit number. If units are expected for a device but not provided, MAKEDEV will supply the standard numbers in most cases.

The i386 supports the following devices:

std
Creates the ‘standard’ devices (console, klog, kmem, ksyms, mem, null, stderr, stdin, stdout, tty, zero) which are absolutely necessary for the system to function properly.
local
Creates configuration-specific devices, by invoking the shell file MAKEDEV.local.
