      @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

        @lostless said in Mausberry Shutdown Script Doesn't Save Metadata:

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

        is it killing the emulator/ES?

            @lostless did you install inotify-tools?

                @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 please, try this one:

                    #!/bin/bash
                    
                    #this is the GPIO pin connected to the lead on switch labeled OUT

                    #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

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

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

                                @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

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

                                  @lostless can you try this one:

                                  #!/bin/bash

                                  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 [ $power = 0 ]; then
                                          sleep 1
                                      else
                                          emu_command="$(sed -n 4p /dev/shm/runcommand.info)"
                                          [[ -n "$emu_command" ]] && pkill -f "${emu_command%% *}" && sleep 12
                                  
                                          espid=$( pgrep -f "/opt/retropie/supplementary/.*/emulationstation([^.]|$)" )
                                          if [ "$espid" ]; then
                                              touch /tmp/es-shutdown && chown pi:pi /tmp/es-shutdown
                                              kill $espid
                                              exit
                                          fi
                                  
                                          sudo poweroff
                                      fi
                                  done
                                  

                                  It's exactly the same script as your Frankenstein, but with a nice indentation. If it works I will try one step further...
                                  I really would like to avoid that loop every single second!

                                    Testing v1.5 from here now....

                                    Take away - Looks like the script is properly closing out of the game I'm playing and returning to ES for a shutdown, but it's not saving the metadata when it shuts that down. I wonder if it's getting hung up in the if functions, not finding a valid true and going to the bottom of the script to the original poweroff without exiting ES first...

                                    You are 100% right.... made a small mistake - I forget to add exit command to break loop! Thank you

                                    So quick question... anybody know how to make a profile in Putty so it can automatically log in (username/password) so I don't have to keep typing it every time I try one of these tests? :)

                                    @lostless - version 1.5 should work now!
                                    Sorry... I forget to exit the loop thanks to @hansolo77 he helped me to detect the bug.

                                    Please mates try again with v1.5 of exit script (with working exit command now)

                                    I give you 100% working guarantee on this ;) You maybe have to extend timer.
                                    I would prefer this to @meleu solution because the sleep timer isn't used if there is no emulator running and the PID is detected and stored as $espid and $emupid This script can be extended to play and/or control backgroundmusic for ex. because it extracts PID

                                    @meleu Do you think you can break the endless 1 second loop?

                                      yes.

                                      I googled about how this device works and I think I found a solution. This is my last atempt...

                                      Some notes about what I found:

                                      • this script is called at boot (/etc/rc.local)

                                      • After changing the script the user needs to reboot to check if it will work.

                                      Some notes about the script below, v1.6 (OK, let's put a version to avoid confusion):

                                      • I think that at the time of calling the file we are monitoring doesn't exist (that's why I'm putting a sleep before monitoring the file.

                                      • I'm not getting why the f&$%k that exit after killing ES is needed. It makes the script stop at the exit, and then the sudo poweroff won't be executed. The strange thing is that the exit is present on v1.2 and @lostless says that it's working...

                                      • before this script needs the inotify-tools installed.

                                      #!/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.

                                        @meleu That's easy....
                                        The exit is needed becasue it ends the mausberry GPIO script and gives control to emulationstation.sh for proper exit

                                        Can you please exchange your lines

                                            emu_command="$(sed -n 4p /dev/shm/runcommand.info)"
                                            [[ -n "$emu_command" ]] && pkill -f "${emu_command%% *}" && sleep 12 # the value of 12 was suggested by @lostless 
                                        

                                        with this one?

                                        emupid="$(sed -n 4p /dev/shm/runcommand.info)"                                #v1.5 @meleu readout 4th line command.info 
                                        emupid="$(pgrep -f "${emupid%% *}")"                                          #v1.5 optain PID emucall by runcommand.sh
                                        
                                        if [ "$emupid" ]; then                                                        #v1.5 check correct PID > avoid sleeptimer if shutdown from ES
                                            kill $emupid && sleep 10
                                        fi    
                                        

                                        It is really the better way. Because you check value of command.info ... this value will also be active if you are back in ES so your [[ -n "$emu_command" ]] is always true and the sleep timer will used in every situation. Even if an emulator is not active. So this would be the last version called 1.6 release :)

                                        This is my last atempt...

                                        Haha ... we will see my friend :)

                                            This is also my last posting on this theme!

                                            We have three working versions now!

                                            meleus version 1.6 which got all features of v1.5 but gots faster GPIO response (breaks 1 second loop, use inotify tool - it's not finished now so WIP)

                                            cyperghosts + meleus version 1.56 which will end ES and all emulators called by runcommand.sh

                                            cyperghosts version 1.2 which just ends ES
