RedHat has this little utility called chkconfig that helps you manage which services get run at which runlevel on startup. It's pretty handy. Its output format is godawful, however:

Quick, what are you running at runlevel 2? How can I easily pick out information? I can't scan the columns very easily. Besides, if you have a table and your values are boolean, don't make them be "Yes" and "No" or "On" and "Off", but a value and empty space.

So here's how I cleaned it up:

  2345  iptables
  2345  network

So much better. Oh my, look, named is only running if I'm at runlevel 5. I wouldn't have noticed that from the first version.

Simple little code follows. Golf it if you must, but I'm not really interested in how I could make it better unless I'm doing something significantly stupid. 
andy@mungo[~]$ more cclist
while (<>) {
    if ( /^(\S+)(\s+\d:o(n|ff)){7}/ ) {
        chomp;
        my @cols = split;
        my $service = shift @cols;
        for ( @cols ) {
            my ( $level, $status ) = split /:/;
            print $status eq "on" ? $level : " ";
        }
        print "\t$service\n";
    } else {
        print;
    }
}
