Running Things Periodically With Launchd

James Duncan Davidson:

I’ve mentioned a few times before in my essays that launchd simply rocks. It can slice, dice, and peel your tomatoes. As is already fairly well covered on the web, it can replace init and watchdog like processes all in one feel swoop. What hasn’t gotten a lot of attention, however, are some of its other talents. In this essay, I’m going to focus on how it replaces cron. Yes, our venerable friend cron is due for replacement and launchd brings on the goodness.
