PINE64 - i3blocks Manjaro battery status script

I did this to have battery-status on the i3bar:

Code:
#!/bin/bash

#simple Shellscript for i3blocks on Pinebook pro

#05012020 geri123@gmx.net Gerhard S.

#battery-symbols: on Manjaro you need the awesome-terminal-fonts package installed!

PERCENT=$(cat /sys/class/power_supply/cw2015-battery/capacity)

STATUS=$(cat /sys/class/power_supply/cw2015-battery/status)

case $((

  $PERCENT >= 0 && $PERCENT <= 20 ? 1 :

  $PERCENT > 20 && $PERCENT <= 40 ? 2 :

  $PERCENT > 40 && $PERCENT <= 60 ? 3 :

  $PERCENT > 60 && $PERCENT <= 80 ? 4 : 5)) in

#

        (1) echo $STATUS::"" ::$PERCENT%;;

        (2) echo $STATUS::"" ::$PERCENT%;;

        (3) echo $STATUS::"" ::$PERCENT%;;

        (4) echo $STATUS::"" ::$PERCENT%;;

        (5) echo $STATUS::"" ::$PERCENT%;;

esac

and in the i3blocks-config:

Code:
[batterystat]

command=sh ~/.config/i3blocks/scripts/batterystat

interval=5
