Battery hook
Folder with custom scripts to be launched in different battery states.
The filename of the scripts, or your custom scripts, must be:
discharging: When the battery is in use.charging: When the battery is charging.low: When it reaches the low percentage. Default 15.high: When it reaches the high percentage. Default 85.full: When the battery is full.
They must have execution permissions. If any of them do not exist, they will be ignored.
Install
curl -o bash-folders-battery-hook https://raw.githubusercontent.com/tanrax/bash-folders/main/bash-folders-battery-hook.sh && chmod +x bash-folders-battery-hook && sudo rm -f /usr/local/bin/bash-folders-battery-hook && sudo mv bash-folders-battery-hook /usr/local/bin && echo "🎉 Successfully installed! 🎉"

mkdir battery-scripts
bash-folders-battery-hook --folder battery-scripts
Inside the folder all the empty scripts will be created, which you will have to edit to include the instructions in Bash.
