    @mediamogul I was going to add it to the shutdown script located in "https://packagecloud.io/kintaro/pcb/packages/raspbian/jessie/kintarosnes_2.4.0_armhf.deb".

    It looks like the install runs it bases on GPIO inputs toggled by the switches.

    Are you saying I'd need to modify the script to toggle the menu item in emulationstation itself? Or that if emulationstation wanted to shutdown, it would need to access the new shutdown script?

      Given your use case, you should only need the first script. I needed the combo, as I launch the script from the Kodi menu of Emulation Station, where I use it to shutdown ES safely and dual boot into OSMC.

        I modified the ES kill portion of this script for my own needs and it's been working out very well for months now. An isolated safe shutdown based on my own would look something like:

        I would add following line before the kill command
        touch /tmp/es-shutdown && chown pi:pi /tmp/es-shutdown

        and then remove the sudo shutdown...

        why?
        Because ES startup scripts checks for presence of es-shutdown file and will initiate a shutdown itself.

        If you use es-sysrestart it will reboot
        use es-restart will restart ES

          Very good to know. I'll add it to my own. Thanks.

            @cyperghost I'll apologize in advance because I'm just starting to learn Linux, so I feel like a middle school kit at Harvard.

            Does that disable the Reboot and shutdown menu's in Emulation station itself?

            Is it possible to run es-shutdown from an external script, in essence shutting down emulation station in the same way that emulation station shuts down the pi?

            My guess would be to replace the "sudo shutdown -h now" with "./path-to/es-shutdown"?

            If I understand, and removing es-shutdown prevents someone from exiting emulationstation from the menu, that may come in handy for my arcade, but I wasn't planning on disabling it for now.

            My goal is to dissect their script so I understand it better, and possibly modify it to shut down the RetroPie more safely.

              No ... it doesn't touch anything on the Graphic-Shutdown-menu

              Is it possible to run es-shutdown from an external script, in essence shutting down emulation station in the same way that emulation station shuts down the pi?

              Yes you can run the script from a external script. You can also modify the script and can path parameters to it.... like ./es_action.sh shutdown to shutdown the Pie
              or ./es_action reboot to Reboot the Pie or just ./es_action quites to terminate ES and go back to terminal.

              My guess would be to replace the "sudo shutdown -h now" with "./path-to/es-shutdown"?

              No just erase that line. ES itself gots a little script that watches for action according to files placed in temp-folder. With touch you set a access date to a file. If the file is not available it will be created. It's better then to redirect like echo > /tmp/es_shutdown

              If you start the script with /path/to/es_shutdown.sh the Pie will shutdown with sudo poweroffcommand hence to the explaination here

              My goal is to dissect their script so I understand it better, and possibly modify it to shut down the RetroPie more safely.

              You can play arround with the script and learn some bash scripting. It isn't so difficult. Don't worry! And welcome to RetroPie

                @cyperghost @mediamogul, I REALLY want to thank you for all your help.

                I'm trying to change careers to Linux admin, and the RetroPie has been my "Carrot" for learning the OS.

                Gradually, I'm picking the stuff up, but responses with information like what is supplied here do more than help me get a toy working, it's something I plan to use for the rest of my life.

                I can only Bury my nose in a CompTIA book for so long before I need some hands on, and this is exactly what I needed.

                Thank you.

                    So, I love Python over Bash...

                    but I cant convert one over the other....

                    Any Ideas how to convert this to python?

                      @mediamogul I am using the original safe shutdown part...

                      import RPi.GPIO as GPIO
                      import os
                      import time
                      
                      
                      ###look at the GPIO for the Button Switch to be depressed
                      
                      GPIO.setmode(GPIO.BCM)
                      GPIO.setup(3, GPIO.IN, pull_up_down=GPIO.PUD_UP)
                      GPIO.wait_for_edge(3, GPIO.FALLING)
                      
                      def main():
                          while True:
                              es-close()
                      
                      def es-close():
                          os.system("/etc/killes.sh")
                      
                      while True:
                          print((es-close))
                          time.sleep(1)
                          os.system("shutdown now")
                      

                      and a very slightly modded es shutdown code

                              @quackwalks that could be the issue, increase the wait time a few seconds because emulationstation takes more time to save the meta data if there are alot of scrapped roms

                                A static wait time really isn't a good idea for something like this. If you use something similar to the while statement in my example above, it will always take as as much time as it needs, no matter what the circumstances.

                                  @drakaen391 About your posted codings.... Does the wait command works in your case? @mediamogul and his while-loop by monitoring PID status is imho better ...

                                  wait can only be used on child processes out of the own subshell
