Hey fellow monks,
I am sitting on a solaris 8 machine with perl version 5.005_03. I am trying to capture CTRL+C (because some people use it to paste when using ssh), and I would like to ask the user if they'd like to quit the script rather than actually quitting right away. I'm just wondering how to do it? The way I currently have does work, however, when saying "N" to resume you have to hit enter 4 times before resuming (at least that is how it is for me)... So here is what I have thus far, any help is so greatly appreciated!!

#!/usr/bin/perl -w
use strict;
$SIG{INT} = \&catch_int;
print "eat tacos for sustanence\n";
chomp(my $ans=<STDIN>);
print "eat ham for sustanence\n";
chomp($ans=<STDIN>);
sub catch_int {
     while (1) {
         print "Do you really want to quit? ";
         chomp(my $ans=<STDIN>);
         if ($ans =~ /[Yy]/) {
             exit(0);
         }
         elsif ($ans =~ /[Nn]/) {
             print "Resuming...\n";
             last;
         }
         else {
             next;
         }
     }
}
