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! 🎉"
Test
bash-folders-battery-hook --help
Run
bash-folders-battery-hook --folder [folder path]
Example.
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.
Start at operating system startup
Option 1: Service
Create a file in /etc/systemd/system/bash-folders-battery-hook.service with the following content.
[Unit]
Description=Folder with custom scripts to be launched in different battery states.

Now you will need the script to run every so often to check the battery status. The best solution is to create a timer.
