Hi!

Maybe this way is useful for you:

use strict;
use Data::Dumper;

sub getServices{

   my $file = "/etc/services";

   open SVCS, $file or die "Error opening $file: $!";

   my $services;

   while( <SVCS> ){
      my %hash;
      next if $_ =~ /^\#/ or $_ =~ /^\s/;
      my ($name, $port_proto) = split /\s+/, $_;
      my ($port, $proto) = split /\//, $port_proto;
      %hash = ( protocol => $proto, port => $port );
      $services->{$name} = \%hash;
    }

   close SVCS;

   return $services;
}

my $returned = &getServices;

print Dumper $returned;

print "Protocol for service FTP: $returned->{ftp}->{protocol}\n";
