        v1.56 works for me. SCUMMVM shuts down immediately without exiting to ES. Is that correct?

          @barrymossel the script is supposed to exit back to es then shut down. Check with other emulators and see if it does that. If not, something is wrong

            Only ScummVM. Probably because than one was an exception. But I don't know whether this would be expected behavior for ScummVM or not. Guess @meleu will tell ;)

              @barrymossel Please can you use PID detector and check PIDs displayed?
              Use ps -a and check PIDs?

                @barrymossel and post the exact script you're using on ghostbin.com or something.

                  If there's any powerblock users, this code works without a hitch with powerblock also, just a simple file edit. How elegant and simple, you guys are awesome!

                  Powerblock proper ES shutdown

                    Sure, when I get back home. What do you want me to do exactly?

                      1. Post code of your current switch bash to ghostbin.com and give us the link
                      2. Run emulator ScummVM
                        2.1 Connect with SSH
                        2.2 Check PIDs (Process ID) during emulator is running
                        2.2.1 Use PID Detector script
                        2.2.2 ps - a if PIDs are equal

                      if PID detector output one number and you type kill PIDNUMBER then the emulator should close :)

                      Because you said your script (version 1.56) does not work with ScummVM so let us invetigate.

                        I actually didn't say it "doesn't work" with ScummVM. It just looks like it doesn't exit to ES first, but it looks like it goes straight to shutdown. I am just wondering if that is expected.

                        But I will do the above in a sec.

                          You see PID Detector says an emulator is running with PID xxxx.

                          What happens if you kill that PID with kill xxxx and can you also enter output of ps -a after the kill command?

                          The script is v 1.56! So it's the newest version.

                              PID TTY          TIME CMD
                              992 tty1     00:00:00 bash
                              997 tty1     00:00:00 bash
                              998 tty1     00:00:00 emulationstatio
                             1005 tty1     00:00:00 emulationstatio
                             1008 tty1     00:01:54 emulationstatio
                             6902 tty1     00:01:00 scummvm
                            10250 pts/0    00:00:00 ps
                            

                            So ScummVM keeps running. I guess, as expected.

                              @barrymossel That's interesting!
                              That's because ScummVM creates itself a bash call.

                                I would change this sentence to: "That's because runcommand starts ScummVM through a bash call."

                                ;-)

                                  @meleu Ready for quick'n'dirty coding? :)

                                  what about a kill $(expr $emupid + "1")
                                  of course you check before if pid is active :)

                                    @cyperghost that behavior reported by @barrymossel was the reason why I was killing the emulator with -9 (SIGKILL). When you kill a bash script with SIGKILL it kills all its child processes.

                                    But I realized that this isn't a good approach for retroarch, because it wouldn't save the .srm file...

                                    Looks like there are room for more improvements on that script. Will post something soon. (edit: or maybe you can do it yourself: just check if the first string on that 4th line is bash, if yes, kill the process with -9)

                                      Ehm, I was wondering: does it even matter that ScummVM doesn't exit to ES before shutdown? Is there any ScummVM meta data anyway? Or wouldn't meta data from games you played before ScummVM be saved either?

                                        Yes for this question.

                                          @meleu Hmm... and if you make case selection?
                                          Are you sure there are no other caveeats? I must admit I'm not very common with the how to kill-a-process method.

                                          okay... I will try :)
                                          It's not tested, i have no access to my Pi now... So just coded out of brain (Please make the code look better... I use lot's of ifs.... much to much!)

                                          emupid="$(sed -n 4p /dev/shm/runcommand.info | tr -d '\\"' | tr '^$[]*.()|+?{}' '.')"
                                          emu_com="$("${emupid%% *}")"
                                          emupid="$(pgrep -f "$emupid")" 
                                          
                                          if [[ "$emu_com" == "bash" ]] && [[ "$emupid" ]]; then
                                              kill -9 $emupid && sleep 4
                                          fi
                                          

                                          You've to check also the PID.... because runcommand.info isn't deleted in ES caroussel mode after emulator is running :)

                                            @barrymossel That's the question. You will losse all your progress in metadata saving if anything goes wrong.

                                            But to be true.... I'm satisfied with 1.56 - the rest are rare usecases (imho)
