I want to plug in the laptop battery charger when the battery level goes down to 40% and then plug it out when the battery charge level reaches 80%. And for that reason, I need a script that would remind me to plug in the charger when the battery level is 40% and again would remind me when the battery charge level reaches 80%. How would be the script? Could anything else do that?
Try this one. In my ubuntu 12.04 it is working perfectly.
#!/bin/bash high=$(cat /sys/class/power_supply/BAT0/charge_full_design) now=$(cat /sys/class/power_supply/BAT0/charge_now) stat=$(cat /sys/class/power_supply/BAT0/status) echo -e "scale=1\n$now/$high * 100\nquit"> hi per=$(bc hi) per=$(expr "$per" : '\(.*\)\..*') if [ $stat == Charging ] ; then if [ $per -gt 80 ] ; then zenity --warning --text="BATTERY IS FULL REMOVE THE CHARGER" fi elif [ $stat == Discharging ] ; then if [ $per -lt 40 ] ; then zenity --warning --text="BATTERY IS LOW PLUGIN THE CHARGER" fi fi rm hi
