I have never done that. It might be possible, I wouldn't know.

There is nothing fragile about cron. It just gets stuff done on schedule. There
is no way (that I know off) to see what cron is doing but it will go ahead and
do what you tell it to do, when you tell it to do it.

Yes, if you want to see some kind of output cron is not the way.
