Which is to say if my system is crashed, was asleep, or powered off when a job is supposed to happen, it will not happen the next time the system is successfully operational, will it? It's not obvious to me for sure either way from any sources I've read (man crontab, google), and unix tends towards k.i.s.s. (which is why we like it) ...I understand why that would be important behavior if something would cause problems executed other than 9am on Mondays... Is there a tool or setting to implement this functionality? I want something to happen weekly, I don't care when. Assume I am off the commercial power grid and I'm not going to leave my system powered on just to make sure my backups get run. I use it when I need it, then I turn it off. More people should. Electricity is not free from a economic, social, or environmental perspective, and promises to be less so with time. Thanks, Steve
