I am trying to run a cron job in Linux with following command:

crontab -e

typing the following details and saving it

MAILTO="[email protected]"
00 01 * * * /usr/local/bin/php /var/www/html/cron.php > /dev/null 2>&1

I am saving this cron job. But it's not running; I'm not getting any output in mail. I don't know how to get details of the cron job which ran. Or is there a better way to run the cron job?

The cron job you pasted will run at 1am daily, and the > /dev/null 2>&1 part ensures that its output is thrown away.

Remove this bit if you intend to receive the script's output by e-mail.

There is a chance that your job is running, but simply failing early (perhaps because the environment provided by cron lacks things provided by your testing environment); we will know once you get the cron e-mail after re-running this job.

  • Yes, it should be server time. Run date to know what that is.

  • I would try running the script every minute with * * * * *, perhaps also redirecting its output to a file (>>/tmp/cron.log 2>&1 instead of what you had).
