show pop-up each minute when battery is 100% charged

Hi all,

How do I show pop-up each minute when battery is 100% charged? Maybe even with some sound...

It does show pop-up only once. I can miss it easily. I'd like to know when it is time to unplug charger in time.

How do I perform it?
Thanks ahead.

Ubuntu 14.04.1 LTS

The battery percentage charge is likely to be found in /sys/class/power_supply/BAT0/capacity.
Popup messages can be created using 'xmessage'.
Sounds can be played using 'aplay'.
Regular checks can be scheduled using 'cron'.

i.e. Write a script that can be run as a cron job.

My actual bash version:

Code:

#!/bin/sh

valuea=`cat /sys/class/power_supply/BAT0/capacity`

echo "$valuea"

if [ $valuea -eq "98" ] || [ $valuea -eq "99" ] || [ $valuea -eq "100" ] || [ $valuea -eq "97" ]

then 

  echo "please unplug charger"

#  xmessage "please unplug charger"

  aplay /home/ymarkiv/Dropbox/music/wav/animals131.wav

  xmessage "please unplug charger"

else 

  echo "still charging"

#  xmessage "still charging"

fi

exit

power_100.sh (END)
