in reply to Re^2: coming out of perl script after 10 min.
in thread coming out of perl script after 10 min.

but my requirement is if the input is not enetered in 20 sec, it should come out of the program(Exit the program).

And that's what the program does (as far as I can tell; but hard to tell, since it is formatted so badly here). Which is why I wonder what your actual question is.
