Get current StartInterval status from Launchd

Question

If a launchd job has a StartInterval of 600 and it's been "some time" since the plist was loaded.

How can one determine how much time remains until the next scheduled run?

Answer 1

It really depends on why you care (inherently, you shouldn't, or more likely, there's some better way to do it). It all comes down to your script being smarter. Drop a turd file or use the script to either defer until next run, or go into a holding pattern.
