in thread control-d out of loop?
Update: There is a way to do this.
However, it is a VI trick.
To input a control-d, you press control-v then a control-d.
This will put a control-d char in variable that you can use to trap for a control-d being pressed.
This code does not have the special char. It is just an example. If you want to try it replace
the ^D with the sequence I described...
$control_d = '^D';
while (chomp($char = <STDIN>)) {
print "control_d $control_d char = $char\n";
if ($char eq '^D) { # control D
print "gotcha\n";
last;
}
}
