in thread sort using <=>
Reading from bottom to top, we construct an array of arrays, where the first element of each element is the sort-field, and the second is the print-field. Then we sort by comparing the sort fields, then we return only the print-fields to print.#open your files as before, then print FOO map { $_->[1] } sort { $a->[0] <=> $b->[0] } map {my @F=split; [substr($F[2],1), $_]} <D>; #close your files as before
