@MDELSHAD - Correct, if you don't have SSH access you wont be able to run that command so you have to do it another way. Uploading files wont preserve your symlinks. Doing what @ty has suggested should allow you to do it also. Running that cron will run as a command via your user on shell. However, once it is symlink'd you would want to remove that cron.. Though if you don't mind me asking who is your host?
@MDELSHAD - Sorry, was referring to the hosting company you are using. Just courius really, as I know most shared hosting now allows ssh, though it's jailed.
