Multi Switch Shutdown Script!
-
@cyperghost Would it possible to adapt your script to work with the new RetroFlag GPi case? It only has a shutdown switch (no reset function). This is the script that is currently supplied by retroflag:
#!/usr/bin/env python3 from gpiozero import Button, LED import os from signal import pause powerPin = 26 powerenPin = 27 hold = 1 power = LED(powerenPin) power.on() #functions that handle button events def when_pressed(): os.system("sudo killall emulationstation && sleep 5s && sudo shutdown -h now") btn = Button(powerPin, hold_time=hold) btn.when_pressed = when_pressed pause()
As you can see they are just using a "sleep" function to handle saving metadata which is not ideal.
-
@quicksilver Yes .... the os.system call has to be changed.
os.system("bash /path/to/multi_switch/multi_switch.sh --es-poweroff")
This will try to close all open emulators and then shutdown the system (after all metadata is saved)
-
@cyperghost That was easy and it works like a charm! Thank you my friend!
-
@cyperghost is there a way to get your script to shutdown if you exit emulation station to the terminal? Or if emulation station crashes or something?
-
@quicksilver said in Multi Switch Shutdown Script!:
is there a way to get your script to shutdown if you exit emulation station to the terminal?
Therefore you can use
.bashrc
from your home directory.
Just add a poweroff command and if you go to terminal the command will be executed.Or if emulation station crashes or something?
You would ask for the PID of Emulationstation simply with
pidof emulationstation
You will obtain the one from the binary and as long this is alive you know ES is running. If there is a change in the PID or the status of SIGNAL has changed you can assume that there someting happend to ES. To determine if it a user action (Reboot, Shutdown...) you watch for files placed into/tmp
dirThe files are
/tmp/es-sysrestart
for sytem wide reboot/tmp/es-restart
for just restarting ES/tmp/es-shutdown
for poweroff
So to answer your question if my script can do this .... only for the
.bashrc
part that is really no rocket science and asudo poweroff
command call would be more effictive.Be aware to not shoot in your own leg with this!

Just wanted to say thanks for this awesome script. After (unsuccessfully) messing around with 'dtoverlay' in config.txt and some years old non-functioning auto-installed stuff, I finally have a single button safe shutdown for ES. Thanks to cyperghost and all involved!
-
SuperPi case, i came from your outdated script that's linked on RetroFlag's github and this script doesn't work. When a game is running, i need to flip the reset button several times then it kills retroarch. Same for shutdown, after 2-3secs "Killed" appears on the screen then it shuts down
-
@danick8989 You to explain in a more clear way. The script can be utilzed in two ways.
- If you use it in pure shell mode then you need to hold the button for one second. The pure bash script uses simple polling to check GPIO state.
- If you "came" from RetroFlag then you utilize python and this uses interrupts so it recognizes button presses instantly. And the lack of "reaction" is likely a faulty case.
Furthermore: if it terminates retroarch and returns you to ES and it shuts down your Pie why are you assuming it's outdated and does not work?
-
@cyperghost I'm not assuming it as outdated, i said i came from your previous revision of the script that's linked on RetroFlag's github page(they didn't update it to this one). And i thought killing retroarch and ES would be discouraged? Like, previously didn't the script send a command to ES for it to close RA properly or something? Also it's not clear to me, how do i use python instead of a bash script, and since it seems to work more seamlessly, why isn't it the default? I rolled back to the old multiswitch script in the meantime, since it still works flawlessly for me aside from exiting from Kodi.

Hi, I kind of hijacked another thread regarding Pegasus, but thought I would ask here instead.
I'm not using a RetroFlag unit, but a Kite Circuit Sword from Sudomod.com
I'm unsure if my shutdown script, the cs_shutdown.sh file in /opt/ folder, does something special that can harm the safe-shutdown process if not built into another script, e.g. your Multi Switch Script. My file looks like this (also mentions a shutdown file?):
#!/bin/bash # Get ES pid ES_PID=`pidof emulationstation` if [[ $ES_PID != "" ]] ; then echo "ES_PID: $ES_PID" # Touch the shutdown file touch /tmp/es-shutdown chown pi:pi /tmp/es-shutdown # Tell ES to terminate kill -s SIGTERM $ES_PID echo "ES has been asked to shutdown" else echo "Could not find ES PID ($ES_PID)" sudo shutdown -h now & fi
Could I just delete this file, and install your Multi Switch Script with the modifications that @SinisterSpatula mentions? Or would I miss something? How much is this solely for RetroFlag builds?
For instance: The RetroFlag is a Pi Zero right? My Circuit Sword is a CM3+ module (not GPIO based, but basically a RPi 3+).
How can I tell if the script works as intended apart from the screen going black?
-
@AndersHP Try replacing
ES_PID=`pidof emulationstation`
with
ES_PID=`pidof pegasus-fe`
or what's the actual process name of the Pegasus front-end. The rest of the script should be the same.
-
@mitu OK thanks, but can I see somehow if everything is working as planned - apart from the obvious thing that Pegasus should quit?
-
@AndersHP The script you posted does nothing more than stopping Pegasus and shutting down, so if comment out the shuttind down part you can check by seeing if the front-end stops.
-
Did the pidof pegasus-fe trick and pegasus quits to terminal now.
But the machine doesn't power off now...? -
@AndersHP your script will just close Pegasus and that's all. you should add a shutdown command to completly shutdown your system.
your (easy) script would more look like...
#!/bin/bash PEGASUS_BIN="pegasus-fe" if [[ -n $(pidof $PEGASUS_BIN) ]] ; then killall -w $PEGASUS_BIN fi sudo poweroff
Much cleaner and more generic than the original one.
If you want the proper exit of all emulators then use this script...
#!/bin/bash PEGASUS_BIN="pegasus-fe" if [[ -n $(pidof $PEGASUS_BIN) ]] ; then bash multi_switch.sh --closeemu killall -w $PEGASUS_BIN fi sudo poweroff
-
But the script literally powered off my Gameboy before I did the ES -> Pegasus change...?
-
@AndersHP But this script does behave like your original one. If you are in terminal and type
sudo poweroff
does then your mashine power off completly?The difference between ES and Pegasus is, that ES uses a "helper" script for shutdown status, therefore the touch-thing.
I think you should be more specific for your setup, which additional scripts are running, how did you install them.....
-
I changed to the above mentioned script, and it does quit and then shutdown. Thanks for the help - will try the Multi Switch script next.
-
@AndersHP Don't forget to setup correct path to to script if you call
bash multi_switch --closeemu
- I know it's sometimes hard to remember doing the things correctly :) -
@cyperghost Id like to use your multi shotdown script with my new argon one case because their script is much less functional than yours. Their argononed.py script looks like this:
import smbus import RPi.GPIO as GPIO import os import time from threading import Thread rev = GPIO.RPI_REVISION if rev == 2 or rev == 3: bus = smbus.SMBus(1) else: bus = smbus.SMBus(0) GPIO.setwarnings(False) GPIO.setmode(GPIO.BCM) shutdown_pin=4 GPIO.setup(shutdown_pin, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) def shutdown_check(): while True: pulsetime = 1 GPIO.wait_for_edge(shutdown_pin, GPIO.RISING) time.sleep(0.01) while GPIO.input(shutdown_pin) == GPIO.HIGH: time.sleep(0.01) pulsetime += 1 if pulsetime >=2 and pulsetime <=3: os.system("reboot") elif pulsetime >=4 and pulsetime <=5: os.system("shutdown now -h") def get_fanspeed(tempval, configlist): for curconfig in configlist: curpair = curconfig.split("=") tempcfg = float(curpair[0]) fancfg = int(float(curpair[1])) if tempval >= tempcfg: return fancfg return 0 def load_config(fname): newconfig = [] try: with open(fname, "r") as fp: for curline in fp: if not curline: continue tmpline = curline.strip() if not tmpline: continue if tmpline[0] == "#": continue tmppair = tmpline.split("=") if len(tmppair) != 2: continue tempval = 0 fanval = 0 try: tempval = float(tmppair[0]) if tempval < 0 or tempval > 100: continue except: continue try: fanval = int(float(tmppair[1])) if fanval < 0 or fanval > 100: continue except: continue newconfig.append( "{:5.1f}={}".format(tempval,fanval)) if len(newconfig) > 0: newconfig.sort(reverse=True) except: return [] return newconfig def temp_check(): fanconfig = ["65=100", "60=55", "55=10"] tmpconfig = load_config("/etc/argononed.conf") if len(tmpconfig) > 0: fanconfig = tmpconfig address=0x1a prevblock=0 while True: temp = os.popen("vcgencmd measure_temp").readline() temp = temp.replace("temp=","") val = float(temp.replace("'C","")) block = get_fanspeed(val, fanconfig) if block < prevblock: time.sleep(30) prevblock = block try: bus.write_byte(address,block) except IOError: temp="" time.sleep(30) try: t1 = Thread(target = shutdown_check) t2 = Thread(target = temp_check) t1.start() t2.start() except: t1.stop() t2.stop() GPIO.cleanup()
I tried changing the os.system to
os.system("bash /path/to/multi_switch/multi_switch.sh --es-poweroff")
like you suggested an earlier time that you helped me but then the reboot and shutdown dont seem to work anymore (I did use the correct path). Obviously I am missing something. I appreciate any guidance you could provide.
