Use Growl to get a warning when your battery reaches a certain percentage (or lower)

growl-battery-warning

Purpose: Use Growl to get a warning when your battery reaches a certain percentage (or lower)

1. Install Growl and growlnotify

2. Save the shell script to /usr/local/bin/growl-battery-warning.sh

3. Make it executable chmod 755 /usr/local/bin/growl-battery-warning.sh

4. Save the plist as "$HOME/Library/LaunchAgents/com.tjluoma.growl-battery-warning.plist" where $HOME stands for your home directory.

5. Enable it by running this command:

   launchctl load "$HOME/Library/LaunchAgents/com.tjluoma.growl-battery-warning.plist"

Need to stop it for awhile?

launchctl unload "$HOME/Library/LaunchAgents/com.tjluoma.growl-battery-warning.plist"

This will stop it until you run the launchctl load command again, or logout/login, or reboot/login.

Want to stop it forever?

launchctl unload "$HOME/Library/LaunchAgents/com.tjluoma.growl-battery-warning.plist"

mv "$HOME/Library/LaunchAgents/com.tjluoma.growl-battery-warning.plist" "$HOME/.Trash/"

"I want to change the threshold for when I get warned!"

Edit /usr/local/bin/growl-battery-warning.sh in a text editor and change this line:

WARNING_THRESHOLD='40'

to something else.

This would make it 30%:

WARNING_THRESHOLD='30'

Note that you do not want to put the % sign in there, just a whole number between 1-100.

"I want to change how often it runs!"

1. Unload the .plist

   launchctl unload "$HOME/Library/LaunchAgents/com.tjluoma.growl-battery-warning.plist"

2. Edit the .plist in a text editor or LaunchControl. The '60' below means 'once every 60 seconds'. Feel free to adjust to your liking. Save the .plist once you have edited the file.

   StartInterval 60

3. Reload the plist:

   launchctl load "$HOME/Library/LaunchAgents/com.tjluoma.growl-battery-warning.plist"
