[LA.pm] Monitoring a directory using Event.pm

[Ofer Nave]

I'm no expert, so I could be wrong, but to my knowledge:

The Event module, unfortunately, has nothing to do with this.  What you 
want is an event-based filesystem, where modifications can trigger 
actions.  The standard linux file system doesn't do this.  There are some 
groovy new FSs that do this, but you probably don't want to go that route.

Although it seems brute force, then best solution is probably write your 
script as daemon (run in the background continuously) and have it 
continuously look for new files to appear (sleep 1 in a loop or 
something).

If you're heart is dead set on making this event driven, then make your 
daemon listen on a port, and modify your client-side code so that it 
connects to that port and sends a message after FTPing the file.
