The /dev directory

The /dev directory contains the special device files for all the devices. The device files are named using special conventions; these are described in Chapter 5. The device files are created during installation, and later with the /dev/MAKEDEV script. The /dev/MAKEDEV.local is a script written by the system administrator that creates local-only device files or links (i.e. those that are not part of the standard MAKEDEV, such as device files for some non-standard device driver).
