Thanks Alex, I appreciate your help. Maybe I should make my question more clearly, I want to make sure the cron job can run in root and had better not require a two-step flow. In your proposed solution, it seems like we need a process periodically check the bandwidth and write the file? What I prefer is that the cron job checks the bandwidth when startd launches.
