I’ve a few cronjobs that run small PHP scripts every 1 or 2 minutes. Obviously I don’t want e-mail every minute. I do want to know when the cron failed or when it encountered any kind of error (= notice, warning, error or uncaught exception).

My PHP scripts print a lot of meta data (using echo) so it can be run manually and inspected. I want all of that meta data to be sent to me IF an error occurred. If no error occurred, I don’t want mail, but because there’s output, cron sends me an e-mail anyway.

Is there a way to have cron ONLY send me the entire output IF an error occurred?

  • I don’t want to manually send an e-mail
  • I rather not use ob (if that’s even possible inside a cronjob)
  • I’m Okay with changing my output method (print or a custom function instead of echo etc)

    Check out crronic – it’s a shell wrapper that provides this functionality:

    Note that you’ll need to exit with a nonzero exit value in case of an error (in order to trigger the mail).
