How to Cron

Hello All,
I have FreePBX I would like to add a cron to run every 5 minutes. I have added a file to /etc/cron.d which contains
*/5 * * * * wget -o /dev/null

It doesn’t seem to be running. Please tell me what am I missing here.

Thank You,

Because this is really a Linux question, you’ll get much more support in a linux focused community, like stackexchange.

The first step would be to log the error. Check your crontab to something like this:
*/5 * * * * wget >> $HOME/cron.log 2>&1

and then look at the $HOME/cron.log file to see what errors are happening.

figured it out. Thank you.


You can put your orders here also.
**/var/spool/cron/**root (file : root, for any scripts using root privileges)
**/var/spool/cron/**asterisk (file : asterisk, for any scripts using asterisk privileges).
In the case where you’ll get some privileges issues.

Hi. Thank you. I read and read and then tried a few times using putty then crontab -e before I realized what was happening there. Finally got that figured out and then it worked. It’s working right now in fact. I just navigated to var/spool/cron/root and my cron is in there in a file called root. Can I rename that file?

Thank You,

Don’t do that. It’s messing with the system at a level meant for people with a lot more experience than you.

For now, just stick with “crontab -eu <username>”, where <username> is either “root” or “asterisk”.
