If you ever need to schedule a job regularly on a Unix system, they have a great utility called cron. This will run a job at a regularly scheduled time.
Here is the format:
* * * * * command to be executed _ _ _ _ _ | | | | | | | | | +--- day of week (0 = Sunday - 6 = Saturday) | | | +----- month (1 - 12) | | +------- day of month (1-31) | +--------- hour(0-23) +----------- minute (0-59)
example of a script that runs every day at 7:
* 7 * * * sendmeupdate
