Pekr ~ yes, easily - as long as that process has sufficient rights, of course. Try this: Open two shell windows on a Unix box: In shell 1 create a file with your favorite editor, save it and keep it open. In shell 2 delete this file and follow this with an ls command - you won't see the file anymore. If you save it again in shell 1 (and it should tell you that it's writing a new file!) and do another ls in shell 2 it will be there again. So semaphores are the better way... Regards, Kai
