How to restart ES from a script?

[BuZz]

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).

[BuZz]

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

@BuZz
Ufff... that was hard stuff!

[TMNTturtlguy]

@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.

[cyperghost]

Wait a moment...

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

[BuZz]

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

[cyperghost]

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

[cyperghost]

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

[TMNTturtlguy]

@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.

[BuZz]

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

[TMNTturtlguy]

@BuZz thanks that seems to work. New issue. When running

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

the script works great, but when i press start and go to QUIT, the screen flashes back to my script and ES restarts. I can't navigate to exit or shutdown. I immediately see the script blue screen and restart ES. So this is not killing the /tmp/es-restart

[cyperghost]

you can please check permission of your Restart Script in retropiemenu.
It must be set to pi.

[TMNTturtlguy]

@cyperghost another beginner questions, how do i check that?

[cyperghost]

@TMNTturtlguy
Because the sh und rp files are called via bash. I'm not 100% sure if this can cause errors. if you never entered SSH as root it's very unlikely you have the wrong permission set.

Sorry late here
ls -al in retropiemenue

[TMNTturtlguy]

@cyperghost everything is set to pi

[TMNTturtlguy]

@TMNTturtlguy @cyperghost @BuZz so i can confirm that

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

Is still not killing all 3 PID. I had to go in and kill, when i did this i got the same blue screen with error text as i posted above using @meleu script. I just tried running this with sudo in front, same effect. Once it is run, entering into the start menu and the retropie menu causes me to immediately flash to the script screen and then restart ES.

[BuZz]

@TMNTturtlguy it's not supposed to kill all the processes - 2 are scripts to launch es which should be left running. Also see above regarding using ps so you can see the full names.
