i3-battery-warning

This is a simple battery warning script. It uses i3's nagbar to display warnings. Let this script run as a cronjob.

Open your crontab:

crontab -e

Add the following line to check battery status every minute:

*/1 * * * * /PATH/TO/YOUR/SCRIPT/i3-batwarn

If the need to trouble shoot arises one could pipe the cron job output to a file like:

*/1 * * * * /PATH/TO/YOUR/SCRIPT/i3-batwarn > /tmp/batterywarn.log

If the script only works when invoked from terminal and not as a crobjob:

*/1 * * * * DISPLAY=:0 /PATH/TO/YOUR/SCRIPT/i3-batwarn
