NAME

MAKEDEV — create system and device special files

SYNOPSIS

DESCRIPTION

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 alpha supports the following devices:

Special device names

all

Creates special files for all devices on alpha.

ramdisk

Ramdisk kernel 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.
