Hi all, I use a python-based program on my webserver to download NZB files.  The program is called hellanzb and resides in /var/www/nzb. To shut the program down if it crashes I have to SSH into the box and execute the following command : [code]python hellanzb.py shutdown[/code] This shuts the program down.  Would it be possible to do this from a button on a web page.  I have tried using the exec() and shell_exec() commands to try and run the command from a php page (pressing a button) but the command doesn't work as the server stays running. What would the code or command be to get this to run ?  Indeed, is it possible to execute a python script from php ? Any help would be appreciated.
