Cron @reboot not working?

Reported by: anonymous Owned by: developers
Priority: normal Milestone: Barrier Breaker 14.07
Component: packages Version: Trunk
Keywords: Cc:


I have a script that I wish to invoke upon a reboot of the OpenWRT router. It works if I schedule every 2 minutes (*/2 * * * *) however, it does not work if I use the '@reboot' command (I want it to run once only upon a reboot).

Is the '@reboot' cron command supported in OpenWRT? I know other Linux versions support it, but unsure if it is a limitation of OpenWRT. If it cannot do it, how can I schedule a script to run upon a reboot?

Cron output shown below.

root@(none):~ $ cat /etc/crontabs/root
@reboot /etc/ssmtp/

I don't know about that cron problem, but you can put startup commands in /etc/rc.local
Perhaps that can help you.

Just put


in the rc.local file, but before the "exit 0" line.
Now it will run that script after every (re)boot.

@reboot is an extension to the BSD crond, not supported by Busybox crond.

Guys, thank you so so much, I really appreicate it.

Anonymous - Putting it in /etc/rc.local works a charm, apologies for the noobness of my question.

Jow - Thanks for also clarifying that @reboot is not supported by Busybox.

You guys rock.
