To emulate cut:
Code:
open my $group, '<', '/etc/group';
my @groups = map { my @a = split /:/; $a[0] . ':' . $a[2] } <$group>;
close $group;

To create a hash mapped on the group name:
Code:
open my $group, '<', '/etc/group';
my %groups = map { my @a = split /:/; $a[0], $a[2] } <$group>;
close $group;
