I had a look at using CGI and stuff, however this has left me thoroughly confused. On my VPS my web folder is ofcourse /var/www so wh开发者_如何转开发ere would i find the cgi-bin folder and how would i go about runing such things? Sorry for such a stupid question :S

You could execute your script like:

exec('/path/to/your/script.sh');
