This script can be used to start and stop your script from any folder when it is placed in “/etc/init.d/”. Start with:

service scriptstarter.sh start

#!/bin/bash
 
#var SERVICE starts the script with nohup and & in the background. the shell can still be used even with the script running.
SERVICE=nohup /home/script/script.sh &
 
#var SERVICENAME is without nohup and & so it will not be shown in the scriptname
SERVICENAME=/home/script/script.sh
 
#if the running script is started with start it will echo "was started", stop = stop, restart = stop,start, anything else will return what you can do.
case "$1" in
start)
	$SERVICE
	[ $? -eq 0 ] && echo "$SERVICENAME was started"
;;
stop)
	pkill -f $SERVICENAME
	[ $? -eq 0 ] && echo "$SERVICENAME was stopped"
;;
restart) 
	$0 stop
	$0 start
;;
*)
	echo "Usage: $0 (start|stop|restart)"
;;
esac

Reason:
Ubuntu says that it cant compare because your variable isnt integer.

Fix:
Use == instead of -eq
