Determine when file is done being written?
One alternative approach is to watch the log of the FTP server to see if the transfer has completed. This would require clever use of File::Tail and possibly the Net::FTPServer::XferLog modules.
The net result of this would be an event-driven methodology (dostuff() to a file when it is transfered in) as opposed to the polling methodology that you're using now.
Not that there's anything wrong with polling. As I say, it's just an alternative. Frankly, I'd be more inclined to do as you are, with the modifications suggested by Weasle.
Hope this helps!
