Как маленький встроенная файловая система Linux может добраться?

Я попробовал эту программу, не лучшую (это анализирует дважды один файл и имеет некоторый дублированный код), но не стесняйтесь адаптировать его к своим потребностям. Я думаю, что это делает работу.

$ cat script.pl
use warnings;
use strict;
use Text::CSV_XS;

my (%col1, %col2);

my $csv = Text::CSV_XS->new(
        { empty_is_undef => 1 }
) or die "Error: " . Text::CSV_XS->error_diag();

chomp( my @data = <STDIN> );

## Read file and save first column in %col1 hash and second
## column in %col2 hash.
foreach my $line ( @data ) {
    die "Error in parse of CSV file\n" unless $csv->parse( $line );
    my @columns = $csv->fields();
    $col1{ $columns[0] }++ if defined $columns[0];
    $col2{ $columns[1] }++ if defined $columns[1];
}

LINE:
foreach my $line ( @data ) {
        die "Error in parse of CSV file\n" unless $csv->parse( $line );
        my @columns = $csv->fields();

        ## Discard line if both columns are undefined.
        next if !defined $columns[0] && !defined $columns[1];

        ## 1.- Undefined first column: Save second column in hash.
        do { $col2{ $columns[1] } = 1; next } unless defined $columns[0];

        ## 2.- Both columns are defined: Sort them.
        if ( defined $columns[0] && defined $columns[1] ) {
                if ( index( $columns[0], $columns[1] ) > -1 ) {
                        # Line is sorted, print it.
                        print quote($columns[0]), ",", quote($columns[1]), "\n";
                        delete $col2{ $columns[1] };
                } else {
                        # Line unsorted, search its equivalent in hash of second column
                        # and print.
                        my $key = $1 if $columns[0] =~ /^(\S*)/;
                        print quote($columns[0]), ",", ( exists $col2{ $key } ? quote($key) : "" ), "\n";
                        delete $col2{ $key } if exists $col2{ $key };
                        # Here, the second unsorted column, search its equivalent in first
                        # column. If not found print it now, else it will be printed later.
                        for my $str ( keys %col1 ) {
                                next LINE if index( $str, $columns[1] ) > -1;
                        }
                        print ",", quote($columns[1]), "\n";
                }
                next;
        }

        ## 3.- Undefined second column: Check if second column is saved in
        ## hash and join it with first column.
        unless ( defined $columns[1] ) {
                my $key = $1 if $columns[0] =~ /^(\S*)/;
                print quote($columns[0]), ",", ( exists $col2{ $key } ? quote($key) : "" ), "\n";
                delete $col2{ $key } if exists $col2{ $key };
        }
}

sub quote {
        my ($str) = $_[0];
        $str =~ s/^(.*)$/"$1"/;
        return $str;
}
