    Scheduling a program/function execution?

    Hey, I'm somewhat new to the GNU world, but I was wondering if it were possible to schedule a function. Basically, if I wanted Function A to run between the hours of 8 AM and 8 PM on such and such a day, and Function B to run between 8 PM and 12 AM, and Function C to run between 12 AM and 8AM, what would I do?

    Under Windows, I know there was a scheduling API. Is there a similar thing for Linux?

    man crontab

    crontab is the program you use to edit the files which control the cron process, which is used to make things happen at regular intervals.

    00 */4 * * * /home/me/jobs
    makes 'jobs' run every 4 hours.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
