That is under-specified. What is the table layout? Spaces only or tabs? With TAB's, have a loog at Text::CSV and it's faster parent Text::CSV_XS. If spaces only, you have a problem, as the first line is not aligned with the rest. If it were, pack/unpack would most likely be of help:
# Example using split on multiple spaces
open my $fh, "<", "INPUT";
while (<$fh>) {
$. < 100 and next;
chomp;
my ($typ, $gid, $org, $lvl) = split m/\s\s+/ => $_;
say "$. $gid, $lvl";
}
close $fh;
# Example with TAB's
use Text::CSV_XS;
open my $fh, "<", "INPUT";
my $csv = Text::CSV_XS->new ({ binary => 1, sep_char => "\t", auto_dia
+g => 1 });
while (my $line = $csv->getline ($fh)) {
$csv->record_number < 100 and next;
my ($typ, $gid, $org, $lvl) = @{$line};
say "$. $gid, $lvl";
}
close $fh;
# Example with unpack (I manually aligned the header line)
open my $fh, "<", "INPUT";
while (<$fh>) {
$. < 100 and next;
chomp;
my ($typ, $gid, $org, $lvl) = unpack "A25 A10 A26 A*" => $_;
say "$. $gid, $lvl";
}
cloase $fh;
