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.
