It is probably an interpolation problem as that string is interpolated by both
perl and the shell. Try it like this:
open my $pipe, '-|', 'yppoll', $nissvr, $map
or die "Cannot open pipe from 'yppoll' $!";
while ( <$pipe> ) {
print +( split )[ -1 ] if /order/;
}
close $pipe or warn $! ? "Error closing 'yppoll' pipe: $!"
: "Exit status $? from 'yppoll'";
