Cron scripts anyone?

[jared]

If anybody on the list knows about cron scripting, i need some help.  (I have no cron experience, 
unfortunately)

I need a script that will take the file "log" for example and move it to /log/(date_goes_here_).log 
and then makes a new blank text file "log" where the first "log" was.  This needs to do this every 
24 hours.  It's a way to keep my logs sorted without doing this manually.

P.S. a short tutorial on where to put the script or how to make it run would be very handy
