We all know the right way to handle output from cron jobs is to redirect it to a file:
0 * * * * /bin/date >> /var/log/date.log 2>&1
However, sometimes admins are lazy, forgetful, or ignorant and don't put in those redirects; in this case the output of the job gets mailed to $MAILTO or the owning user or root. On some of the boxes I manage, mail is disabled, so this output goes into a black hole. What I'm wondering is, is there any way to tell cron to take any job output and instead of mailing it, throw it into a catch-all log file somewhere? I'm using Ubuntu (8.04 but migrating to 9.04). There's a hint of such a solution in this random Google result, but I think the OP might have been confused about cron output vs. the output of cron jobs.
I'm open to solutions that involve a bit of scripting or hacking, but ideally this would be a config bit I could set somewhere. I don't see any hints in
man cron. Thanks!
