Pass parameters via url inside a php cron job

Hi there, I would like to run a php file via cron job and there is a parameter to be passed. Unfortunatelly this does not work: # /usr/local/bin/php /home/www/create_notification_emails.php?tf=2 Could not open input file: /home/www/create_notification_emails.php?tf=2 The problem seems to be the ?tf=2 How do I pass parameters to this script? I need the same script but executed in different time frames which is passed by the parameter. Any ideas? Thank you for any hint, Merlin
