input-utils: utilities for the input layer of the Linux kernel: This is a collection of utilities which are useful when working with the input layer of the Linux kernel (version 2.6 and later).

- input-events - observe input events for watching a specific input device, must specify the device number such as 'sudo input-events 3'
