Thanks for the addition comments.
The statement Bill offers above is exactly what I was looking for. And I
went through all of the information given in this thread and realized I
was trying to solve the wrong problem.
What I was after was the ip address (aka 192.168.2.13) and the only way
I could see to get it was through the ip command which needed a token to
grep for. That token is what I wanted to be a single known name. My
understanding of the situation now is that is not how things work.
Since I couldn't find a single command which would get me the static ip
of the wired connection, I decided to just use hostname as the important
thing was "a unique name". I originally didn't want to do that as names
are changeable, but then I realized that the same holds true for static
ip addresses ... if I can change a hostname, I can change a static ip.
I considered MAC address, but it looked like I was back to the problem
of using ip and grepping on a potentially different token per machine.
Problem is solved as far as I am concerned, even though I am certain
there is probably some way to get a unique token. Since my goal is to
get the machine up and running so I can be a user on it, I learned from
all the material offered that it is best to cut my losses.
Once again, I thank everyone for their help ... I've got a much better
understand of just what eth0 and em1 are (smile)
