Web Auto Update (Linux + PHP)

In my project, the controller will be place at the remote site (like sabah & sawarak) and having sluggish internet connection. I need the controller to automatic update the firmware during the transfer.

How to do it?

1. download the update script.
   

   wget http://192.168.0.8/ipvision-client/tools/autoupdate.php?id=IPV0001 -O autoupdate.sh
   

2. Change the script file permission to allow execute.
   /bin/chmod 777 autoupdate.sh
   
   
3. Execute the script
   
   bin/sh /tmp/autoupdate.sh
   
   
4. update the status, so this operation not reoccur.
   
   wget http://192.168.0.8/ipvision-client/tools/autoupdate.php?id=IPV0001&action=done
   
   
5. put the script on cron job.
