For the url you've posted, the command would be:
php -q /home/ehiagwina/public_html/crons/are/not/4u/braveupdate.php
However, I'd suggeset that you put it in something other than your public_html folder, like /etc, so that people can't trigger the job by just visiting the page.
And like t2t2 said, make sure that your email is entered, and you check it. To test the CRON job out, set it for 5 minutes. Be sure you change it after you've received the first one, though!
