Restart ES via bash script!

[cyperghost]

Dear user the feature richest version is here posting #6 - please use this!

---

Edit: abolished version (yet functional)

Edit: lazy way pkill -n emulationstatio
works exactly as the script ... just kills the latest process of ES

KEEP CARE! You have to use touch /tmp/es-restart before using the restart commands!

The trick is do not to kill all childs. I think it has something to do with the SDL framework.

Create file home/pi/RetroPie/retropiemenu/Restart ES.sh
copy code in
make it executable, Restart ES manually via menu (hopefully last time)
Then Restart ES is selectable via RetroPie Menu

That was really hard to resolve!

#!/bin/bash
# by cyperghost
# 06/16/2017
# That was rocking hard!
echo "Create es-restart"
sudo touch "/tmp/es-restart"
echo "Kill latest process PID of ES"
sleep 3
kill $(pgrep -l -n emulationstatio | awk '!/grep/ {printf "%s ",$1}')
sudo rm -f "/tmp/es-restart"

Was there a need for that language ?

@cyperghost awesome! Do I have your permission to add this code into my script for each of the Es change functions? I don't see the need for this in the retropie menu but rather right within my script for my use case. Thanks for figuring this out so quickly!

[cyperghost]

@BuZz No, but this drive me nuts .... I knew there is a solution!

• I listed the cpp code of ES
• watched services from RetroPie
• listed bash scripts from ES
• ...and yes ES checks for the existance of empty description files

So my first intension not to kill all child processes was 100% right but then I looked to @TMNTturtlguy script and in the file '/usr/bin/emulationstation' is the path to victory :)

Next time I use "EUREKA", right?

@TMNTturtlguy of course you can use this in your script. Just write a small contribution within. But please be aware of future changes in ES.

I'm very thankfull for your attempts because I asked me why you want to create empty files. But they are important for the boot staring progress.

Again: Please take care of future version. This script just kills the latest PID of ES!

New coder new solution - @BuZz created a nice two liner

RetroPie-setup 4.2.8 needed (released 06/16/2017)

#!/bin/bash
#Restart ES via Bash script v1.1
#06/16/2017 v1.0
#intensive rework done by BuZz all greetings fly out to him
#special thank to @TMNTturtlguy  for bug hunting!
#version 06/17/17 slightly modified by meleu
touch /tmp/es-restart
pkill -f "/opt/retropie/supplementary/.*/emulationstation([^.]|$)"

It was tested several times by @BuZz @TMNTturtlguy and myself.

How to:
Copy this script to /home/pi/RetroPie/retropiemenu/´ Create bash file like Restart ES`there
Give file permission and user pi:pi 755

Attention: RetroPie-setup < 4.2.8 (realease date 06/16/2017) should use sudo -u pi touch /tmp/es-restart

That resolves problems with data permission!

@cyperghost with the latest retropie-setup you can remove the sudo -u pi btw.

[cyperghost]

done

[BuZz]

@cyperghost (retropie-setup 4.2.8)

[cyperghost]

@BuZz clearly written!
Made Bash rework

pi@retropie:~ $ touch /tmp/es-restart
pi@retropie:~ $ pkill -f -e "/opt/retropie/supplementary/.*/emulationstation$"
emulationstatio killed (pid 999)

Only one PID killed! Three alive!

Hi,

Sorry I know this is an old thread but thought it was relevant to my question :)

Currently using 4.4

My script below, it works fine but it outputs:

rm: cannot remove '/tmp/es-restart': Operation not permitted

Script

#!/usr/bin/env bash
rm /opt/retropie/configs/all/emulationstation/es_settings.cfg
cp /opt/retropie/configs/all/emulationstation/emulationstation_swap/megadrivejapanmini/es_settings.cfg /opt/retropie/configs/all/emulationstation/ 
        echo -e "\n\n\n                               Theme set to: Mega Drive Japan mini\n\n\n"

sudo touch "/tmp/es-restart"
sleep 3
kill $(pgrep -l -n emulationstatio | awk '!/grep/ {printf "%s ",$1}')
sudo rm -f "/tmp/es-restart"

I currently have it to swap out the es_settings.cfg file but going to adapt it to search es_settings.cfg for the actual text command and change on the fly but for now I'm just trying to see what the options are for restarting ES after the first initial command has been activated.

Would just like to know if there is a new approach to restarting es without the use of es-restart ?

@paffley You should start a new topic.

[paffley]

@mitu said in Restart ES via bash script!:

@paffley You should start a new topic.

Thanks @mitu I solved my problem so no need to start a new topic. I also changed from rm/cp to the grep command to edit the existing es_settings.cfg

I did the above so I could change themes from within the retropie system whilst in Kiosk mode, also have done the same for screen ratio's and overlays :)

Cheers!
