launchctl/launchd cheat sheet

I've never had great understanding of launchctl but the deprecation of the old commands with launchctl 2 (10.10) has been terrible as all resources only cover the old commands, and documentation for Apple utilities is generally disgracefully bad, with launchctl not dissembling.

Mad props to https://babodee.wordpress.com/2016/04/09/launchctl-2-0-syntax/ which contains most details

domains

Internally, launchd has several domains, but launchctl 1 would only ask for service names,

Cycle through available audio devices with key binds(shift+a,ctrl+a). Change "wasapi" on line 1 to your relevant audio api.
local api = "wasapi"
local deviceList = mp.get_property_native("audio-device-list")
local aid = 1
local function cycle_adevice(s, e, d)
mp.enable_messages("error")
while s ~= e + d do -- until the loop would cycle back to the number we started on
if string.find(mp.get_property("audio-device"), deviceList[s].name, 1, true) then
while true do
if s + d == 0 then --the device list starts at 1; 0 means we iterated to far
s = #deviceList + 1 --so lets restart at the last device

Rename files with a hash based on their contents. eg: `abc.jpg` to `3101ace8db9f.jpg`. Useful for detecting duplicates.
