[launchd-dev] WatchPaths

[Brian Hanson]

On the same subject, and apologies if this has been addressed elsewhere (I searched the archives to no avail), but does WatchPaths have the ability to pass the name (or path) of the item that triggered the job? In other words, using AppleScript folder actions, one can get the name of the item received in the folder. Is there a similar way to get this with WatchPaths? The receiving folder could have hundreds of files in it, so iterating through the folder, looking at mod dates, etc, wouldn't be stable enough.
