Apple launchctl


I have a console app running on a Mac server - set up to run every x minutes using LaunchControl app ( All works great.

Question: is it at all possible to unload the job, edit the .plist file for this job (to say, change the StartInterval property) and then reload it from within the console app itself? (I’m guessing it will involve the use of launchctl in a shell, but not sure about permissions etc).

Any help/pointers, as always, appreciated.
