Untested (assuming 2500 lines as cut-of)

  1. my @csv_files = map { $_->[0] } sort { $a->[1] <=> $b->[1] } map { [ $_, -s ] } glob "*.csv"
  2. my @csv = map { @{csv (in => $_, headers => "skip")} } @csv_files;
  3. use Text::CSV_XS qw( csv );
    use PerlIO::via::gzip;
    my $n = "0000";
    while (@csv) {
  4.     open my $fh, ">:via(gzip)", "new".$n++.".csv.gz";
        csv (in => [ splice @csv, 0, (@csv > 2500 ? 2500 : $#csv) ], out => $fh);}
        }

Enjoy, Have FUN! H.Merijn
