Init Service Script

SH
The script that runs as a service and calls the Python script
#!/bin/sh

### BEGIN INIT INFO

# Provides:          myservice

# Required-Start:    $remote_fs $syslog

# Required-Stop:     $remote_fs $syslog

# Default-Start:     2 3 4 5

# Default-Stop:      0 1 6

# Short-Description: Put a short description of the service here

# Description:       Put a long description of the service here

### END INIT INFO

# Change the next 3 lines to suit where you install your script and what you want$

DIR=/home/pi

DAEMON=$DIR/TestScript.py

DAEMON_NAME=myTestService


# Add any command line options for your daemon here

DAEMON_OPTS=""

# This next line determines what user the script runs as.

# Root generally not recommended but necessary if you are using the Raspberry Pi $

DAEMON_USER=root


# The process ID of the script when it runs is stored here:

PIDFILE=/var/run/$DAEMON_NAME.pid

. /lib/lsb/init-functions

  #Add "--exec $DAEMON" ^^^ (replace --us$) //for OSMC

  log_end_msg $?

}

do_stop () {

  log_daemon_msg "Stopping system $DAEMON_NAME daemon"

  start-stop-daemon --stop --pidfile $PIDFILE --retry 10

TestScript.py

Python
Python Startup script which calls for shutdown on an interrupt to a pin.
#!/usr/bin/env python

import RPi.GPIO as PINS
import os

PINS.setmode(PINS.BCM)

from time import sleep

PINS.setup(18,PINS.IN, pull_up_down=PINS.PUD_UP)

def returnprint(channel):
  print"Trigger happened!"
  os.system("sudo shutdown -h now")

PINS.add_event_detect(18,PINS.FALLING, callback=returnprint, bouncetime=400)

while True:

  sleep(10)
