The low level approach would be select, which does exactly that, and on Unix systems also works on filehandles. On Win32, you would have to use WaitForMultipleObjects to get select-like functionality.

But most likely, you want a framework that calls your function(s) whenever something interesting happens, and POE is such a framework. Most likely POE::Wheel::File::Tail does what you want.
