user-input

I am trying to make an interactive shell script in perl.

The only user input I can find is the following:
$name = <STDIN>;
print STDOUT "Hello $name\n";

But in this the user must always press enter for the changes to take effect. How can I get the program to proceed immediately after a button has been pressed?
