UNIX command for checking the cron job failures?
Hi- I need to set a mail trap for checking the cron job filures in a server.

I have many cron jobs running in our server. What unix command will identify the failed cron jobs?

Your thoughts please!!!!!

Hello ChandruBala73,

If you are the root for your system then you can check the cron logs at /var/log/cron at the first place.

Thanks,

Hi,

You don't say what your flavour of Unix is, however all you should have to do is;

Code:
vi /etc/crontab

And change the MAILTO variable to the destination required. Then all that should be required is to redirect standard error to standard out for your scripts/cron jobs.

Regards

Dave

Hi,

You will have to request some assistance from your admin team, although you should remember that any user (if allowed) may use the cron daemon and have their own crontab file - where the output from any cron jobs including mails will be sent to that user.

Regards

By default every output, stdout or stderr, is causing a mail to userid@server.
You can redirect it in the crontab like this
Code:
* * * * * { yourcommand; } 2>&1 | mail yourmail@address

cron should log results to syslog; mayhap your admins can hand you an extract on a daily basis?
