Go back and reread my posting; you do so by using the "crontab" command.

No, in the current implementations shipped by AT&T, it's done by sending
something over a named pipe.  HOWEVER, this does not necessarily mean
that it's done that way on implementations done independently of the
AT&T code, nor does it necessarily mean that it'll be done that way in
all AT&T versions henceforth and forever more, world without end, amen.

Moral: use the "crontab" command.  Don't depend on the unpublished
details of a particular implementation.
