Here is the output. Not sure if cron isn't running or other issue. If I issue
curl --silent http://..../scanner.php from terminal, I'm getting desired output. Actually scanner.php do some check and send an email. I've getting that. But not working from cron. Can you please advice me how can I detect the issue?
Edit: I have fixed the issue by adding a space before "&" and a new line after the command. Thanks all.
