script to change the framework laptop power led color based on battery/charging status. I use it as a cron job

framework_powerled_color.sh

#!/bin/bash

# takes desired critical percentage as first argument and
# charged percentage as second, both with default values.
# example usages:
#
# framework_powerled_color.sh
# framework_powerled_color.sh 10
# framework_powerled_color.sh 10 98
#
# requires cat and fw-ectool

CAPACITY=$(cat /sys/class/power_supply/BAT1/capacity)
PLUGGED=$(cat /sys/class/power_supply/ACAD/online)
CRITICAL=${1:-10}
CHARGED=${2:-98}

if [ "$PLUGGED" -eq "1" ]; then
    if [ "$CAPACITY" -lt "$CHARGED" ]; then
        fw-ectool led power amber
    else
        fw-ectool led power white
    fi
elif [ "$CAPACITY" -le "$CRITICAL" ]; then
    fw-ectool led power red
else
    fw-ectool led power white
fi
