Cron Job For importing Feeds

I am trying to setup cron job for a feed, but it does not work and I need to import it manually

I entered

/bin/curl -O /dev/null "http://benton.k12.ia.us/index.php?option=com_easyblog&task=cronfeed"; >/dev/null 2>&1

any advice for what changes need to be made, my hosting provider had me add the curl...

thanks
