Increases or decreases the screen brightness

1. Download or clone this repo;
2. Exec chmod +x bright;
3. Move bright to your path: sudo mv path/to/bright /usr/local/bin

IMPORTANT! You must execute sudo chmod o+w /sys/class/backlight/intel_backlight/brightness so that you can use this script without super user privileges.

• bright up will increase the screen brightness 5%.
• bright down will decrease the screen brightness 5%.

• This was tested only for my personal needs (Ubuntu 18.04) since my new wireless keyboard has no function keys to control brightness. With this script, I was able to set new shortcuts to increase and decrease it.
• This script changes /sys/class/backlight/intel_backlight only. If you need to change dell_backlight or something else maybe you could adapt this.
