data import in cronjob


I am running version 2.03 and do not have support anymore to upgrade to a newer version. Anyhow i have fixed many bugs myself in this version.

What i want to do now is import a datafeed an a daily basis. Manually this works fine through admin–>administration–>import.

Now the problem is that i need to run this import command in a linux shell, so i can put it in the crontab.

Does anyone know how to achieve this?
