No, I know that. But last time I checked the documentation I didn't find what I searched. But today, when I looked again the document was bigger and contained what I needed.
As if just parts of the document was loaded last time I opened it.
So it works now.
I know basic Cron stuff, what tgpx suggested however was to build it by pointing to a text file, that was a bit beoynd me.
Thanks for the answer though
