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...

Kai
