MBS( "FSEvents.UUIDForDevice" ) More
Parameters
none
Result
Returns UUID or error.
Description
Gets the UUID associated with a device.Returns empty text if not possible (for example, on read-only device).
A (non-empty) UUID uniquely identifies a given stream of FSEvents. If this (non-empty) UUID is different than one that you stored from a previous run then the event stream is different (for example, because FSEvents were purged, because the disk was erased, or because the event ID counter wrapped around back to zero). An empty return value indicates that "historical" events are not available, i.e., you should not supply a "sinceWhen" value to FSEvents.Create other than "now".
The UUID is returned as 32 hex characters.
Examples
Queries UUID for root:
MBS( "FSEvents.UUIDForDevice"; "/" )
