Cron is a time-based job scheduler, which is useful to run something periodically at fixed times, dates, or intervals. It typically automates system maintenance or administration.
opkg install cron
Check the name of super user on your system. If it's other then root, please fix it at /opt/etc/crontab. As an example, asuswrt(-merlin) uses admin:
sed -i 's/root/admin/g' /opt/etc/crontab
Please, refer to Vixie's crontab format to add new jobs to /opt/etc/crontab. Cron package contains some helper scripts, you may put some jobs (shell scripts or symlinks) to following folders:
/opt/etc/cron.1min
/opt/etc/cron.5mins
/opt/etc/cron.daily
/opt/etc/cron.hourly
/opt/etc/cron.monthly
/opt/etc/cron.weekly
and run cron by:
/opt/etc/init.d/S10cron start
Cron will be started automatically boot.
