To come full circle on this topic, the point of the arp vs. ip n show
disscusion was my attempt to expand what comes out of lpstat -v to
include MAC. I deal with a customer that chooses not to configure
printers with either reserved IP or static IP and if there is a major
disruption, we have to go chasing down printers.
Did I mention that this customer is in Lake Charles, LA? Can you say
two hurricanes in one year? I thought you could...
So here is the synopsis of what I came up with for my and your future
reference.
- lpstat -v > somefile.txt
massage somefile.txt to remove non-relevant printers, i.e. those at
other locations not affected by said hurricane
-create a handy printmung.sed script
s_device for _echo "_
s_ socket://_" `ip n show _
s_:9100_`_
(note the "_" is the edit delimiter so as to avoid conflict with the
"//" in line two.)
- cat somefile.txt | sed -f printmung.sed > myscript.sh
- edit myscript.sh to include the #!/bin/bash and check things over
- chmod 755 myscript.sh
-./myscript.sh > nextfile.txt
YMMV

I figured out ip n show and it's output is actually cleaner than arp -a.

Howard,
Shell functions in .bashrc for the win!
arp() {
if [ "$1" = "-v" ]
then
ip -s neigh
else
ip neigh
fi
}
Not a perfect example, since I'm typing this on my phone, but enough
to give a start if you have a mind to do so.
However, I'm old, cranky, and don't need to change 30 some years of
knowing arp, ifconfig, etc. for the "convenience" of the new kids
coming into IT... LOL! I'm sure that I will be working on these at
some point.
I hope that everyone has a great weekend!

Subject: [nlug] Whaddyamean net-tools is deprecated???
I am not the most versed student of the arp command so I hit the man
page to get more info only to see, in passing, that the entire
net-tools
package is now "obsolete" and no longer maintained. Okay, I admit that
I have gotten prior hints about that with the ifconfig command as well.
No more arp, hello ip n.
So I've searched up this cheat sheet:
<https://iamhow.com/Technical_Notes/Replacement_commands_for_net-tools_cheatsheet.html>
Swell.
Remember all of our grousing about systemd? grouse, grouse, grouse,
grouse...
