There is no way to inform the shell ->at the beginning of the line<- that it
will be redirecting stdout and/or stderr.

I have used this type of construct in my crontab (your times will, of course, vary):

1 12 * * * /home/elucas/bin/cronscript >> /home/elucas/log/cronscript.log 2>&1

That redirects stdout and stderr to append to the log file.

Yes, "ugly" cron.  How often do little children stop in the street, point to
you, and taunt "your crontab is ugly... your crontab is ugly"?
Why would you care?  They are just sysadmins^H^H^H^H^H^H^H^H^H^*children* after all!

Hope that helps... or at least gives you a laugh.
