The code below is pretty simple but I can't figure out why it is not printing the hash key? I'm sure someone here can figure it out in a matter of seconds where I have been looking at it for over an hour.
use strict;
use warnings;
my %hash = (
'asdf.com' => 'asdf',
'abc.123.com' => '123',
'just.me.com' => 'me',
'just.you.com' => 'you',
'new.domain.com' => 'new',
'newest.domain.com' => 'newest'
);
print "\nPossibly domain names: \n\n";
foreach my $key (keys %hash) {
print " $key\n";
}
print "\nWhat is the domain name of this server? \n";
my $selection = <>;
chomp $selection;
foreach my $key (keys %hash) {
if ($key eq $selection) {
print "\n";
}else{
print "\nThe domain you entered is not on the list above. Now
+ exiting script.\n";
exit;
}
}
Thank you in advance.
