Got an email when run cron job for every 15 minutes of particular URL in Cent OS

I set cron job with every 15 minutes for particular URL in Cent OS. But, i did not return any email. i get an email with below contents when every 15 minutes runs the cron. How to avoid email notification.

Cron job for 15 min:

*/15 * * * * /usr/bin/curl http://domain.com/cronprocess 2>&1 >> /var/www/html/cron.log

The redirection operator 2>&1 needs to go after the redirection to the log file, if that's what you intended. There is also an option (-q IIRC) to suppress the progress indicator from curl.

*/15 * * * * /usr/bin/curl http://domain.com/cronprocess >>/var/www/html/cron.log 2>&1

or probably more likely

*/15 * * * * /usr/bin/curl -q http://domain.com/cronprocess >>/var/www/html/cron.log 2>&1

Edit: So to emphasize, you are setting up curl to output the fetched page to cron.log. I would not call it sane behavior to also append the error messages to that log file, but since you already had the 2>&1 there, I assume that's really what you want. The way you had it, it would do the redirections in the wrong order; it would redirect standard error to standard output, then redirect standard output to be appended to the file (but not standard error, which would remain connected to your original standard output).
