In the below code, once one of the error messages have been matched, how do you tell Expect not to try and match anything else because the command prompt is always returned? In short, the command prompt is always matched, $err_flg never gets set regardless if one of the error messages is matched or not. 
sub work ()
{
    my $err_flg = 0;
 
    $exp->send("command\r");
    $exp->expect(5,
        [ qr/ERROR MESSAGE 1/i, sub { my $self = shift;
            sleep(1);
            $err_flg = 1; }],
        [ qr/ERROR MESSAGE 2/i, sub { my $self = shift;
            sleep(1);
            $err_flg = 1; }],
        [ qr/command prompt/i, sub { my $self = shift;
            sleep(1);
            $self->send("command\r"); }]
    ) or return(1);
    if ($err_flg == 1)
    {
        return(1);
    }
 
    return(0);
}
