Bonjour si je me base un peu sur les deux scripts existants pour connecter ma manette avec un service qui lanche le bash j'aurai fait ainsi C'est de la pure théorie, sauvegarde ton image avant. Je n'ai pas compris si switch.sh était juste un fichier d'installation ou d’exécution script switch.sh

echo '#!/bin/bash

#this is the GPIO pin connected to the lead on switch labeled OUT
GPIOpin1=23

#this is the GPIO pin connected to the lead on switch labeled IN
GPIOpin2=24

echo "$GPIOpin1" > /sys/class/gpio/export
echo "in" > /sys/class/gpio/gpio$GPIOpin1/direction
echo "$GPIOpin2" > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio$GPIOpin2/direction
echo "1" > /sys/class/gpio/gpio$GPIOpin2/value
while [ 1 = 1 ]; do
power=$(cat /sys/class/gpio/gpio$GPIOpin1/value)
if [ $power = 0 ]; then
sleep 1
else
sudo poweroff
fi
done' > /recalbox/scripts/switch.sh
chmod 777 /recalbox/scripts/switch.sh

Puis basé sur le Btservice de ma manette que j'ai adapté , A nommer S92sw

serviceStatus() {
   if [ ! -z "$BTD_PID" ]; then
      echo -e '33[0mservice switch.sh ['$BTD_PID'] [33[33;32m OK 33[0m]'
   else
      echo -e '33[0mservice switch.sh [33[33;31m KO 33[0m]'
   fi
}

# Carry out specific functions when asked to by the system
case "$1" in
   start)
      echo "Starting script $RUN ..."
      if [ -z "$BTD_PID" ]; then
         nice -n 19 $RUN&

         if [ $? -eq 0 ]; then
            echo -e "33[0mscript $RUN [33[33;32m STARTED 33[0m]"
         fi
      else
         echo "script $RUN already started ['$BTD_PID']!"
      fi
      #serviceStatus
   ;;
   stop)
      echo "Stopping script $RUN ..."
      if [ ! -z "$BTD_PID" ]; then
         kill $BTD_PID

         if [ $? -eq 0 ]; then
            echo -e "33[0mscript $RUN [33[33;31m STOPPED 33[0m]"
         fi
      fi
      #serviceStatus
   ;;
   status)
      serviceStatus
   ;;
   *)
      echo "Usage: /etc/init.d/SwitchService {start | stop | status}"
      exit 1
   ;;
esac

exit 0

Faire un chmod 777 /etc/init.d/S92sw Ensuite tester :

/etc/init.d/S92sw start
/etc/init.d/S92sw stop
/etc/init.d/S92sw status

et ensuite redémarre le rpi2 pour voir si ça lance tout seul. attention il faut attendre quelques secondes pour que le service démarre.
