Action triggered by file/directory change (inotify) #32
Description
(originally from StreamController/StreamController#206)
While working on a script that I have StreamController run, I thought it would have been nice if there was a way to run the script when some external event occurred (in my case when a file was added or removed from a directory). I used the run every x seconds feature in the OS Run Command action. That works, but does cause the commands to get run a lot when most of the time nothing will have changed.
So I propose that StreamController use inotify (or something similar) and a new config section be added to OS Run Command to specify what kind of event on what file/directory to watch for. When the inotify event is triggered, the specified command is run.
There may be other actions besides OS Run Command, where this would be useful.
