cron on debian 4.0, what use have the cron.xxxx folders?
 

I am running debian 4.0 and thought, the folders under /etc labeled cron.daily, cron.weekly etc are for scripts that are executed on that basis.

So I wrote simple .sh scripts and copied them into the dirs. Nothing happens!

Why? Can somebody shed some light onto the overall concept?
Do I have to fiddle with crontab...?

What permissions did you apply to the script?

in /etc/cron.daily its a symbolic link (all permission) owned by root

pointing to /root

where the script had very limited permissions. I changed this now to 0755.

Still, it doesn't work.

Anyone with a short introduction to the overall cron layout/functionality on debian 4.0?

So far, I have found this post about how the cron directories / crontab works.
