this already does it

   http://freepan.org/ruby/by-dist/fs-watcher/

check out the testsuite for examples

you would probably use it like:


     watcher = FileSystemWatcher.new("condor_outdir", "*")
     watcher.sleepTime = 1
     watcher.start { |status,file|
       if status == FileSystemWatcher::CREATED then
         puts "#{ file } was created"
       elsif status == FileSystemWatcher::MODIFIED then
         puts "#{ file } was modified"
       elsif status == FileSystemWatcher::DELETED then
         puts "#{ file } was deleted"
       end
     }

cheers.
