I removed mrtg because I wasn't using it, and now I have a cron trying to execute it and filling up my mail box because its failing.

I probably did this the wrong way but I need to stop it so I don't have 800+ emails.

Here is the email thats getting sent to me:

/bin/bash: /usr/bin/mrtg: No such file or directory

Thats all I know, how can I find out username and remove it from the crontab?

Nevermind found it in /etc/crontab

Dumb.
