hi guys, i'm working with bash, i'm creating a script that check the battery status and the wall carger status to do some things like keep battery life disabling some features (wifi, 3g mode, ringtone, vibration, bluetooth, fmradio, etc)

can somone help me? the script has to save the current profile if different from silent, i made some mistakes and i'm a little bit confused with it becouse it doesnt save the right used profile.

this is the code i made

**** the code is in test for that i left "battery.charge_level.percentage = " empty to test it better
