make cron perform a chmod?

im not too familiar with cron jobs, as i only use them to run single files .. but is there anyway to make cron jobs cmod certain files and/or directories?

edit-- this would be into my control panel, like hSphere or cPanel

I think you need to tell some script waht you want to do.

one option is to run all scripts inside a directory while using php (and this one script is executed by cron

You can use cron to chmod a file, but the cron user must have rights to do this.

And please don't ask me how I am so sure about this, because last time I got hacked this was exactly what the hackers did :)

i assume with a shared hosting account, you wont have access to chmod files with cron :(
