I need to enable power (AC) failure (off-line) and power on (on-line) notifications, like this notification:

I searched and tried to do that, but I didn't find any successful articles. I use these commands to monitor my AC adapter:

acpi- a



echo ac_adapter=$(acpi -a | cut -d' ' -f3 | cut -d- -f1)

But I don't know how to write notification on code.

Can I write a shell script like the following?

#!/bin/bash



power=ac_adapter=$(acpi -a | cut -d' ' -f3 | cut -d- -f1)

s1="$power"





if [ "$s1" = "off-line" ]; then



    notify-send  --urgency=low "Power Manager" "Power Down" -i battery_low

    echo "notification: off" >~/.scripts/notification



else

  if [ $s1 = "on-line" ]; then

    notify-send  --urgency=normal "Power Manager" "Power Up" -i battery_full
