Mausberry Shutdown Script Doesn't Save Metadata

meleu

@lostless please, install inotify-tools:

sudo apt-get install inotify-tools

and then try the script below:

#!/bin/bash
# Before using this script you need to install inotify-tools:
#
#    sudo apt-get install inotify-tools
#
# I'm just trying to help with the script logic here.
# I DON'T HAVE A MAUSEBERRY AND DIDN'T TEST THE GPIO STUFF HERE!

@meleu Im giving it a shot. I really don't want to reconfigure my pi, but oh what the heck. Ive only had to reconfigure 10 times or so. whats another for the most perfect script for mauseberry (or other switch) users.

meleu

@lostless I edited the script, be sure to get the current one!

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...
