brightnessctl

Small tool for linux to adjust screen brightness.

npm install -g brightnessctl

Tested on the Dell XPS13 running Arch.

Usage

To adjust the screen brightness simply run

sudo brightnessctl

It will print an interactive slider that looks like this:

Use <left> and <right> to adjust brightness
[#######                                        ]  15%

You can also adjust the brightness with a cli argument like so

sudo brightnessctl 50 # sets the brightness to 50%

PRs that add support for more distros welcome.
