I have a script that ultimately asks the user for input. I want to use that input to search against the hash. For simplicity sake we will say if the input is found in the hash it will print "found" if not it will print "not found" Here is a snippet of the bottom of the code. My assumption is the exist doesn't report efficiently because it isn't comparing the user input to the hash. 
my $username = "$lname, $fname";
%new_hash;
$new_hash{$username} = $password;

while()
{
        print "Please enter a last name and a frist name.\n";
        chomp ($input =<STDIN>);
                {
        foreach ($input)
                {
        if (exists $new_hash{$username})
                {
        print "The username is $username and the password is $new_hash
+{$username}\n";
                last;
                }
        else
                {
        print "I'm sorry, there is no one here by that name!\n";
                last;
                }
}
