      @BuZz Wait I post output in a few minutes...

      pi@retropie:~ $ ls /tmp
      es-restart  omxplayerdbus.root  omxplayerdbus.root.pid
      pi@retropie:~ $ ps -a
        PID TTY          TIME CMD
        862 tty1     00:00:00 bash
        867 tty1     00:00:00 bash
        868 tty1     00:00:00 emulationstatio
        874 tty1     00:00:00 emulationstatio
        877 tty1     00:00:13 emulationstatio
        990 pts/0    00:00:00 ps
      

      The command pkill

      pi@retropie:~ $ pkill -f -e "/emulationstation$"
      emulationstatio killed (pid 868)
      emulationstatio killed (pid 877)
      

      check with ps -a

      pi@retropie:~ $ ps -a
        PID TTY          TIME CMD
        862 tty1     00:00:00 bash
        874 tty1     00:00:00 emulationstatio
       1001 tty1     00:00:08 emulationstatio
       1071 pts/0    00:00:00 ps
      

      worked now... sorry... but 2 PIDs alive
      If PID 874 in my current setup will be killed than ES is wrecked.

      Thank you

        @cyperghost use ps -fa as you can't tell what they are from that. probably parent bash scripts (which is correct - they shouldn't be killed).

          touch /tmp/es-restart; killall -e "/opt/retropie/supplementary/emulationstation/emulationstation"

          runs fine all 3 PIDs are up to date

          When i use this in my script, it runs the first time. The second time i try to run it, the script crashes with error "cant remove /tmp/es-restart

                @TMNTturtlguy said in How to restart ES from a script?:

                @BuZz @cyperghost

                touch /tmp/es-restart; killall -e "/opt/retropie/supplementary/emulationstation/emulationstation"

                When i use this in my script, it runs the first time. The second time i try to run it, the script crashes with error "cant remove /tmp/es-restart

                because custom retropie scripts are actually run as root - ill change that I think, but just make sure you create it owned by pi for now.

                sudo -u pi touch /tmp/es-restart
                pkill -f "/emulationstation$"

                    @BuZz What is your prefered method?
                    pkill or killall? I think pkill offers more room for changes.

                      I have updated retropie-setup so user scripts will now be launched as a normal user without elevated permissions (can use sudo in a script if needed).

                        @cyperghost pkill so it can kill emulationstation running from any path.

                            @cyperghost @BuZz i updated retropie-setup and now i can't run my script, and i also cannot do anything within the retropie setup script either. I enter restropie setup, it freezes up for a bit and then exits back to the retropie menu.

                                @TMNTturtlguy did you reboot ? you may want to sudo rm /tmp/es-restart also.

                                  There is a problem after launching the first time. Will check.

                                    @BuZz There seems to be a problem with the one lost PID!
                                    I did not update but I'm facing the same problem!

                                      No the first killall script runs in best condition!
                                      All 3 PIDs are running there!

                                      touch /tmp/es-restart; killall -e "/opt/retropie/supplementary/emulationstation/emulationstation"
                                      

                                      and I can execute @TMNTturtlguy script like usual behavior.

                                        @cyperghost the pkill isn't working as it also kills a needed parent process as the pattern matches a bash line which I missed.

                                        touch /tmp/es-restart
                                        pkill -f "/opt/retropie/supplementary/.*/emulationstation$"
                                        

                                        should sort it

                                          @cyperghost @BuZz Ok, so I did the ps -a and killed the largest emulationstatio and i can at least navigate the menus again....so yes the pkill is causing the issue,

                                          Next issue is after the setup script update my script gives an error saying that '/opt/retropie/configs/all/emulationstation/es_systems.cfg' is write protected and the script errors out.

                                            @TMNTturtlguy if your script wants to edit that file it will need to use sudo as user scripts are no longer run as root.
