looking for a unix script to check dedi server status

Hi, as you know, dedi server will hang eventually after a few days/weeks, for IW4M I had a nice rcon php script to check server through rcon and if not responding, restart the server via pkill...

but for IW5M, I can not find such script to issue any rcon command...

I don't want to install B3 and all extra stuff, just want to be able to do a simple rcon gametype via a script...

Is it possible??

#!/bin/bash

HOST=localhost
PORT=28960
RCONPASSWD=mypassword
SERVER=./restart-tdm1.sh
CHECKER=./rcon/rconcmd.php

while true; do
RES1=''
RES2=''
RES3=''

RES1=$(php $CHECKER "--ip="$HOST "--port="$PORT "--password="$RCONPASSWD "--command=g_gametype")
sleep 10;

RES2=$(php $CHECKER "--ip="$HOST "--port="$PORT "--password="$RCONPASSWD "--command=g_gametype")
sleep 10;

RES3=$(php $CHECKER "--ip="$HOST "--port="$PORT "--password="$RCONPASSWD "--command=g_gametype")
sleep 10;

if [ -z "$RES1" ]; then
if [ -z "$RES2" ]; then
if [ -z "$RES3" ]; then
echo
echo "Server is down, restarting"
date
echo
echo
$SERVER &
fi
fi
fi

sleep 60;
done
