in reply to split line

You're trying to split on a separator that is literally a space between quote marks. Instead, you want to split on any amount of consecutive whitespace:

my @config = split /\s+/, $line

Note that you have leading spaces in your string; you may want to strip those out before splitting.

    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.
