Mausberry Shutdown Script Doesn't Save Metadata

[lostless]

@meleu i saw that. whew.

[lostless]

@meleu killed all switch functionality. As in it no longer functions as a shutdown switch.

[meleu]

@lostless OK. I'll try a little further...

[lostless]

@meleu i see you removed some stuff from the original script

while [ 1 = 1 ]; do
power=$(cat /sys/class/gpio/gpio$GPIOpin1/value)
if [ $power = 0 ]; then
sleep 1
else

that was removed. any reason to that?

yep. This infinite loop is consuming CPU cycles unnecessarily.

[lostless]

@meleu that was in the original script from mauseberry. never had any issues. interesting that their code just constantly checks the gpio.

[meleu]

@lostless do they have a github repo or something?

[lostless]

@meleu they don't. just the download and install instructions on their website. But heres the script you download and install.

echo '#!/bin/bash

#this is the GPIO pin connected to the lead on switch labeled OUT
GPIOpin1=23

#this is the GPIO pin connected to the lead on switch labeled IN
GPIOpin2=24

echo "$GPIOpin1" > /sys/class/gpio/export
echo "in" > /sys/class/gpio/gpio$GPIOpin1/direction
echo "$GPIOpin2" > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio$GPIOpin2/direction
echo "1" > /sys/class/gpio/gpio$GPIOpin2/value
while [ 1 = 1 ]; do
power=$(cat /sys/class/gpio/gpio$GPIOpin1/value)
if [ $power = 0 ]; then
sleep 1
else
sudo poweroff
fi
done

is it killing the emulator/ES?

[lostless]

@meleu its not doing anything.

[meleu]

@lostless did you install inotify-tools?

[lostless]

@meleu yes

[meleu]

@lostless OK, let's try with that expensive infinite loop just to check if the inotifywait part is bugging the script. Hold on a little...

[lostless]

@meleu I'm trying my own Frankenste in script (taking the parts that i see may work)

[meleu]

@lostless please, try this one:

#!/bin/bash
 
#this is the GPIO pin connected to the lead on switch labeled OUT
GPIOpin1=23
 
#this is the GPIO pin connected to the lead on switch labeled IN
GPIOpin2=24
 
echo "$GPIOpin1" > /sys/class/gpio/export
echo "in" > /sys/class/gpio/gpio$GPIOpin1/direction
echo "$GPIOpin2" > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio$GPIOpin2/direction
echo "1" > /sys/class/gpio/gpio$GPIOpin2/value
 
file="/sys/class/gpio/gpio$GPIOpin1/value"
 
while true; do
    power="$(cat "$file")"
    if [[ "$power" == 0 ]];
        sleep 1
    else
        emu_command="$(sed -n 4p /dev/shm/runcommand.info)"
        [[ -n "$emu_command" ]] && pkill -f "${emu_command%% *}" && sleep 5
 
        espid=$(pgrep -f "/opt/retropie/supplementary/.*/emulationstation([^.]|$)")
        if [[ "$espid" ]]; then
            touch /tmp/es-shutdown && chown pi:pi /tmp/es-shutdown
            kill "$espid"
        fi
 
        sudo poweroff
    fi
done

@meleu your new script is still doing nothing and mine worked just like the 1.2.

[meleu]

@lostless helping with this blind coding is very hard. I'm giving up...

[lostless]

@meleu sounds good man. it was fun. the 1.2 works fine, a lot better then always losing meta data all the time.

[meleu]

@lostless where is this script placed? what directory?

[lostless]

@meleu location is /etc/switch.sh
