      @meleu Sounds good, i have to do real work as well. I will be away from my pi all weekend, so we might have to resume this on sunday or monday.

      @cyperghost I am 99% sure that your method worked, my only concern was your statement about what happens when we update ES. I want this to work for all users as you just suggested in your latest post. This is why i tried @meleu method as it appeared to more straight forward. Problem is that now i can't run either anymore because for some reason @meleu code might have done something in the background?

        @TMNTturtlguy No there is no difference in mine or meleus method. Both methods can run into trouble!

            @TMNTturtlguy hey bro, Linux shell is very rigorous with typing! :)

            • use emulationstat not emulastionstat
            • use /tmp/ not /temp

                @TMNTturtlguy Please don't get me wrong he needed the PID.
                Edit: Sorry for that kind of work! I know you just want to help :)

                @meleu

                868 emulationstatio
                874 emulationstatio
                877 emulationstatio
                

                That are three PIDs
                I kill only 877

                output of mine
                via echo 
                echo $(pgrep -l -n emulationstatio | awk '!/grep/ {printf "%s ",$1}')
                
                results:
                877
                
                I kill 877 with
                kill 877
                
                after checking again I see 3 PIDs
                868
                874
                1026
                

                your command

                I use e param for listing:
                pkill -f -e "/opt/retropie/supplementary.*emulationstation([^.]|$)"
                emulationstatio killed (pid 874)
                emulationstatio killed (pid 877)
                

                after

                with:
                pgrep -lf emulationstat
                nothing
                

                So the whole system is killed!

                  Here is the touch line - this is the same error i get when i run from my script and what happens now when i use @cyperghost script a 2nd time. First, this is what i typed in when retropie was running properly:
                  0_1497624115417_37c5b6a5-f5de-465b-8d0e-b1b656449c04-image.png

                  And here is the outcome on the pi - no output in putty command line

                  0_1497624026016_error.png

                  running pgerp -lf emulationstat now gives no output at all.
                  when i touch a button on my controller i exit to a black screen on the pi, have to sudo reboot.

                    @TMNTturtlguy Please delete /tmp/es-restart manually
                    What has OMX-Player to do with Emulationstation?

                    pleas @TMNTturtlguy
                    Try this in shell output of ps -a

                    in shell

                    echo $(pgrep -l -n emulationstatio | awk '!/grep/ {printf "%s ",$1}')
                    

                    No worries you can't make mistakes with that. That are all output commands.

                      @cyperghost that is the thing, i don't have a /tmp/es-restart to delete, it isn't there! I am pretty confused, when i did my attempts running touch es-restart I always got a /tmp/ file. any issues, just sudo rm and it was fixed. Now i don't see a /tmp/es-restart file, however it is retaining the error screen from @meleu script.

                      As you might be able to tell, i am not a coder, so i am really stretching here creating this stuff. It is fun, but there is a lot I don't understand. Can you provide more info on what you want me to do? Not sure what you mean by :

                      Try this in shell output of ps -a
                      in shell
                      echo $(pgrep -l -n emulationstatio | awk '!/grep/ {printf "%s ",$1}')

                        @TMNTturtlguy I'll sort it this evening, but when that happens with your terminal try to (maybe blindly) type reset and press enter.

                          @TMNTturtlguy
                          connect via SSH
                          in prompt type ps -a
                          That list all process with tty1 output

                          then create the file es-restart with sudo command
                          sudo touch /tmp/es-restart

                          check existance with
                          ls /tmp

                          into the ps list... take the pid from ES with the highst number (that's the latest processes) and type
                          kill 1234 your PID here should not be 1234 ;)

                          after that

                          ps -a
                          again... What do you see?

                            @cyperghost maybe ps -a | grep emulationsta can give a cleaner output for him. :)

                              @meleu well that are only 2 or three more processes - clean enough but thank you ;)

                              @TMNTturtlguy I'm also not a coder - I made my master degree in chemistry

                                @cyperghost thanks for explaining!

                                To answer your question from the previous post - OMX is the screensaver running, part of a new update to ES.

                                here is my output - when i ran the kill line, it killed the screensaver.

                                  yes that's it...

                                  You see so it works...
                                  You killed ES with PID 941

                                  This was terminated

                                  and relaunched as new
                                  ES with PID 1500

                                  meleus script would kill
                                  938 and 941
                                  you can check with (the -e parameter shows list of killed PIDs)

                                  pkill -f -e "/opt/retropie/supplementary.*emulationstation([^.]|$)"
                                  

                                  after meleus script all emulationstation PIDs are gone >> dead!

                                    @cyperghost What's the problem with sending a SIGINT to all processes rather than one ?

                                    @TMNTturtlguy es-restart will get removed by the ES launch script hence why it disappears.

                                      @BuZz Well ... You are the coding wizard :)

                                      I think if you show us a way to solve this proper please go on.
                                      Maybe you can make this waterproof? Or tell us something behind the scene of RetroPie?

                                        @cyperghost I'm not sure what the problem is ? :)

                                        [edit] is it still the same issue as in the OP ? I'd have to test, but it should be ok to killall on ES, which would also kill the current running script of course as it's a child process itself.

                                            That did it! Success....I am now back to running without getting the errors. @cyperghost your script does work well. I am going to upload the update to github. If you are willing it would be great for you to test. It is easy for you to delete the script after testing if you don't find it useful. Thanks for all the help. Will be interested to see how updates to ES will affect this.
