    Does anyone have any practical or clever 'outside of the box' ideas they use cron jobs for?

    Sadly I only use it for work, but maybe you could schedule a job that runs a script, which will email you the football results.

    When I was teaching students about cronjobs, I made them set a cronjob to e-mail me a Christmas greeting at 4:00am on Christmas morning (this wasn't in Ireland, so the novelty factor actually made it interesting).

    It all went well apart from one student didn't get it to work so actually got out of bed on the day in question to send me the e-mail, totally missing the point of the exercise. :D

    True story.

    Well I'd say that was a valuable lesson illustrating why cron was written in the first place! :pac:

    I have a somewhat dodgy router (drops connections once in a blue moon and needs a reboot). I have a cron job running on a raspberry pi that checks for this and automatically reboots the router for me when this happens.
