in thread split line

this works except for the first element, the first element still gets blank. Is there any way to chomp the begining?

    dwm042's answer below does this but there's a shortcut specifically for this kind of thing. Try this:

    my $line = " 0 10 9 4 1 0 0 0 2 2 1 1 0"; my @config = grep /\S/, split / /, $line; # or even my @config = grep /\A\d+\z/, split / /, $line; print join(", ", @config), "\n";

    The second will only pass through numbers (well, positive integers and zero) so something like "6a" will be skipped.
