Good, reading is always good, but write code from day 0 ...

You can run an Elisp file like a shell script (not literally),
with Emacs,

  $ emacs --batch --load FILE

I'd recommend making that work _in_ Emacs first, then as
above, only the third step would be from cron ...

Here is an example, with emphasis on AN example, not saying
it's a GOOD example of program design ...

  https://dataswamp.org/~incal/emacs-init/piles.el
  https://dataswamp.org/~incal/hits/hits.gpi
  https://dataswamp.org/~incal/piles-all

With

  $ crontab -l
  30 2 * * * /home/incal/public_html/hits/piles-all; 
/home/incal/public_html/hits/hits.gpi

It's a cool pic anyway :)

If you feel you don't know enough Lisp start with things at
a level where you can get going ... those very small programs
don't have to be useful. Typically you don't have to write so
many of those before you can actually start with things that
are simple yes but actually useful as well.
