MAKEDEV —
create system and device special files
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. Files are created in the current working directory.
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 amd64 supports the following devices:
Special device names
- all
- Creates special files for all devices on amd64.
- 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.
