Troubles with Cron job settings

Hi.
I have my own hosting server which i can access through WHM and my cpanel - my issue is i am trying to setup remote publishing from email and im not sure how to setup the cron job command

changing the domain from your suggested one it would be :

/bin/wget -O /dev/null "http://www.evanstransport.co.uk/index.php?option=com_easyblog&task=cron";

I assume the first part isnt right but i really havent a clue what it should be?
I have never setup a cron job before sop be gentle with me please !

thanks for assistance
