brightnessctl

A simple brightness controller. It helps change device values like keyboards and displays. You point to the directory with a max_brightness and brightness interface, and specify an amount. Everything else is 👌.

$ ./brightnessctl --help
Usage of ./brightnessctl:
  -amount int
        Increate or decreate by this percentage. Ex: 5 or -5. (default 5)
  -device string
        The options are 'keyboard' or 'display' or '/sys/class/etcetcetc'.
