Mausberry Shutdown Script Doesn't Save Metadata

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

lostless

@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

lostless

@meleu My frankenstein script is working. Thank you so much for giving me insight. I know i didnt contribute anything to the code, but I feel like a kid in the 80/90s, discovering computers before they were made easy to use.
i found you need to give time for retroarch to quit and emulation station to reload before you try quit emulation station. i gave it 12 seconds. 5 was not enough, by the time the emulator quit, emulation station was not fully loaded back in.

here is what i came up with

#!/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

# End Emulationstation if condition of running binary is true
# v1.0 07/21/17 by cyperghost - Inital run 
# v1.1 07/22/17 - Added chown command to set right user permission for creating es-shutdown
# v1.2 07/23/17 - Some small improvments, easier to maintain, removed echo, removed else branch 
# v1.works 7/27/17 (are we even trying to number this)  @lostless figured it out. More time to quit emulator and reload emulation station before shutdown. @cyperghost  thank you for initial run. @meleu thank you for your insight
        emu_command="$(sed -n 4p /dev/shm/runcommand.info)"
        [[ -n "$emu_command" ]] && pkill -f "${emu_command%% *}" && sleep 12

espid=$( pgrep -f "/opt/retropie/supplementary/.*/emulationstation([^.]|$)" ) # detect PID of ES binary only
if [ "$espid" ]; then
   touch /tmp/es-shutdown && chown pi:pi /tmp/es-shutdown
   kill $espid
   exit
fi
# End Emulationstation if condition of running binary is true

sudo poweroff
fi
done

@cyperghost Thank you for the first script up to 1.2.
@hansolo77 give this a try. its working for me quite well.
