Isn't this the kind of thing that FAM was invented for?

(Or specific things like inotify on Linux: http://en.wikipedia.org/wiki/Inotify )

(as in your process monitors the directory itself and picks up the renames without having to be signalled by another process - although you could just give it a SIGHUP when another process using FAM/inotify notices the rename but why complexify things?)

But then, process will have to continuously keep a check on the directory. So, the time interval will need to be figured out for the process to wake up and check the directory for the renames.

It seems that inotify will be perfect for my requirement. Thanks a lot..
