this makes no sense at all - you *know* that the file is created -  
you don't *care* if find sees it.  all you need to do is

require  'fileutils'

Dir.glob('**/**') do |src|
   next if test ?d, src

   dst = "Mod-#{ src }"

   cmd = "app #{ src }"
   system cmd

   abort "<#{ cmd }> failed with <#{ $?.inspect }>" unless
     $?.exitstatus.zero? and test ?e, dst

   FileUtils.rm_f src
   FileUtils.mv dst, src
end

or am i missing something here?

cheers.
