[...]
The file '.shrc' has the following:
[...]

I've tested this and it works.
here, too, thanks!!
One -w switches from 80 column width to 132 column width, but two -w's

It works for me, and I suspect that it's working for you, too.
well, it's really not. The crontab execution is trying to run the daemon
even when the daemon shows up in ps aux.
Well, it was just a guess. :) I tested against my 'named' daemon, using the
