Problems getting init.d service to start on boot

[hp2024]

I'm trying to get a shell script to start running at boot. It's a basic while loop that copies files into a directory then sleeps for 30 seconds. It starts and runs fine when I start the service myself, but it never seems to be running after bootup.

My sync.sh script

#!/bin/sh
syncdirectory="$HOME/syncdirectory"
targetdirectory="$HOME/targetdirectory"

while :
do
    cp -a $syncdirectory/* $targetdirectory
    sleep 30
done

My init.d service file

#!/bin/sh /etc/rc.common
 
START=95
USE_PROCD=1

start_service() {
        procd_open_instance
        procd_set_param command sh $HOME/sync.sh 
        procd_set_param respawn  # respawn the service if it exits
        procd_close_instance
}

In my install script I'm running

cp $HOME/sync /etc/init.d/
chmod +x /etc/init.d/sync
chmod +x $HOME/sync.sh
/etc/init.d/sync enable
/etc/init.d/sync start

Any input would be greatly appreciated as I've been struggling with this for too long. I've even tried starting it in rc.local but that doesn't seem to be working either.

I've also tried not using PROCD. Runs fine if I manually start it, but never on boot.

#!/bin/sh /etc/rc.common
 
START=95

start() {        
    sh $HOME/sync.sh &
 }

Is $HOME defined for a non-interactive session? Try with hard-coded paths or add logger "HOME is $HOME" at the top of the script to see what value it has.

Yeah that's exactly what the problem was. Adding the full path made it start working. Thanks!
