Starting bash script on boot

Hi all,

Hopefully its an easy fix, I'm trying to start a bash script at startup that will run forever (while system is online).

I have a script, called statupdate

I have located it in /etc/init.d/

I have given it execute permissions

I have then put in a link to it under /etc/init.d/RC3.d/S99statupdate

This worked, but the system boot sequence never finished because the script started kept looping, preventing the system boot sequence to continue.

I then created another script called startupdate

that script simply started the main statupdate script. I tried with the following:

./statupdate &

OR

nohup ./statupdate &

I swapped out the S99statupdate with S99startupdate (and gave it execute permissions)

The exact same issue occured.

Can anyone point out what I'm doing wrong?

Cheers,
Pazu

I have tried the following but get an error 'unknown service' when trying to add with chkconfig

#!/bin/bash
#
# Run-level Startup script for the LCD Stat Updater
#
# chkconfig: 345 91 19
# description: Startup/Shutdown LCD Stat Updater

# if the executables do not exist -- display error

if [ ! -f /etc/init.d/statupdate ]
then
        echo "LCDStatusMon startup: cannot start"
        exit 1
fi

# depending on parameter -- startup, shutdown, restart 
# of the instance and listener or usage display 

case "$1" in
    start)
        # LCDStatusMon  startup
        echo -n "Starting LCD Status Monitor: "
        /etc/init.d/statupdate
        echo "OK"
        ;;
    stop)
 	# LCDStatusMon shutdown
        echo -n "Shutdown LCD Status Monitor: "
        pkill -f statupdate
        echo "OK"

    *)
        echo "Usage: $0 start|stop|restart|reload"
        exit 1
esac
exit 0
