I'll probably never be the best in the field...
I don't know how to start this but here goes.
I've been "using" Linux for over 10 years, possibly more and I still feel like I'm nowhere
where I should be. I'll be fair most of my time was spent either figuring out how
to run games on *nix at the time but as I got older and "wiser" I started learning
more about it. I do credit my dad for opening up the world of *nix to me as
he was more of a networks type of guy.
Long story short, I was blessed with a job working with Unix systems; Solaris & IBM i series.
I'm able to get tasks from my senior fairly done without much questioning from him I still feel
I'm light years behind, I don't know why but it seems that's so much more than #echo "hello world".
I guess I'm just venting, this is my first sysadmin job ever and, it was a huge jump from
being in tech support for a year and half. A few times I surprised my senior but, I don't know...
feels like I'm missing something.

I want to sort alphabetically on the first field and sort in descending numerical order on the 2nd field. With a normal "sort -r -n" it does this:

NAME
fair -- simple TCP load balancing service
DESCRIPTION
fair is a load balancer for TCP connections. It can be used to distribute incoming connections for SMTP, HTTP or any other TCP service to
multiple hosts, distributing the load as evenly as possible.
fair consists of two daemons. The carrousel is the front-end; it keeps track of back-end hosts and their status, and forwards incoming con-
nections to the back-ends in such a way that the load is distributed fairly. The transponder runs on the back-end hosts, it registers with
the carrousel and sends it status information. The TCP connections forwarded by the carrousel are not sent to the transponder daemons but
are sent directly to the desired service running on the back-end host. Both daemons share a single configuration file.
EXAMPLES
The following example shows how to set up fair to service HTTP connections and to distribute them over back-ends in the 192.168.1.0/24 sub-
net.
The configuration file /etc/fair.conf contains the following:
WorkerService = http
BalancerService = http
AllowUDP = ^192.168.1.[0-9]+$
On www.example.com, the front-end server receiving the incoming HTTP connections, just run:
carrousel
On each of the back-ends run:
transponder www.example.com
