I don't see what is wrong with chkconfig's output. If you are interested in one specific service you can do either "chkconfig --list someservice" or "chkconfig --list | grep someservice". If you want to know which services run in runlevel 2, you can do "chkconfig --list | grep 2:on".
I want to look at all of them, at a glance. The "on" and "off" strings are unnecessarily obscuring. The best way to say "no" is with whitespace. It makes you think, rather than make the answers incredibly obvious.
Do you honestly not see the difference between the default output and what I put together?
I really liked your idea. I couldn't help but golf a little. I only output what's on.
/sbin/chkconfig --list | perl -nle '$s=(split)[0];s/(\d):on/$a{$s}.=$1/ge;s/(\w+):\s+(on)/$a{"xinetd -> $1"}=$2/e; END{print "$_: $a{$_}" for sort keys %a}'
Score
yours: 186 swings; 147 swings if I turn all your vars into single characters.
mine: 116 swings.
Just having fun!
