Export log in mail body

Hi,

I have set up an automatic backup job in crontab for the database. It works as expected.

After execting the cronjob I get mail from the user. And it contains the complete log file of Export.

How do I prevent going complete Export log file in the mail

Thanks

Sameer

Send the output of your job to /dev/null

exp system@xyz file=xyz.dmp log=xyz.log > /dev/null 2>&1
