Running PHP from the shell or CRON???

Hi, I am trying to run PHP from a shell via telnet. I am testing this because I eventually want to have a CRON job running this PHP script every day. The PHP script will simply check a site, parse the page and select some info to update a MySQL db. So I issue either one of the following shell command: %php mytest.php or %php ./mytest.php and received the following error: ~~~~~~~~~~~~~~~~~~~~~~~~~~ X-Powered-By: PHP/4.0.1.pl2 Content-type: text/html <br> <b>Fatal Error</b>: Unable to open mytest in <b>Unknown</b> on line <b>0</b><br> ~~~~~~~~~~~~~~~~~~~~~~~~~~~ I am runnuing this command for a cgi-bin where I have both PHP and mytest.php in it. cgi-bin is not in my path. So my question is can PHP be executed from the shell or from a CRON job, if yes what is the problem with the above? Thanks Claude C
