Battery notification bash script

Shell Programming and Scripting

Lol you're right.
I havent looked that closely at the script anymore - because it seems to work :smiley:

But, if i adjust the code, it wont work as expected.

[~/prjs/SWARM] 0 $ DATA_RAW=$(LC_ALL=C acpi)
[~/prjs/SWARM] 0 $ echo "$DATA_RAW" | awk -v IFS="," '{print $3}' | tr -d ','
Discharging
[~/prjs/SWARM] 0 $ echo "$DATA_RAW" | awk -v FS="," '{print $3}' | tr -d ','
 discharging at zero rate - will never fully discharge.

I think the issue here is the DATA_RAW input, which has no further ',' after 'discharging', so using the proper FS, will make the the 3rd field 'too long' as it wont limit it to words anymore.
Thus actualy removing the requirement for FS=", " alltogether!

Why did I add that FS though.... :thinking: :upside_down_face:

Wrote several scripts over the past week or so & I've finally got one that works.. Here's the code....

#!/usr/bin/env bash
set -x
while true
do
    export DISPLAY=:0.0
    battery=$(acpi -b | grep -P -o '[0-9]+(?=%)')
    echo $battery
  if [[ $battery -eq 100 ]]; then
        notify-send -i "/usr/share/icons/Arc-X-P/panel/22/battery-full-charged.svg" "Battery Charged" "Level: ${battery}%"
      elif [[ $battery -le 22 ]]; then
        yad --no-buttons --center --borders=22 --timeout=22 --title="BATTERY LOW. PLEASE PLUG IN CHARGER...." --image /home/furycd001/Terminal/Selena\ Gomez/batterylow.jpg
      fi
    sleep 2m
done
