Assuming there's no spaces in the csv, you could do: awk -F, '{print $0,$3}' | sort -k2 | uniq -D -f 1 | awk '{print $1}' eg: $ cat 1 Normal,Server,xldspntcs01,10.33.16.198, Normal,Server,xldspntc02,,10.33.52.185, Normal,Server,xldsps01,10.33.16.162, Normal,Server,xldspntc04,,10.33.52.187, Normal,Server,xldspntcs01,,10.33.16.199, Normal,Server,xldsps02,10.33.16.163, Normal,Server,xldspntc02,,10.33.52.186, $ cat 1 | awk -F, '{print $0,$3}' | sort -k2 | uniq -D -f 1 | awk '{print $1}' Normal,Server,xldspntc02,,10.33.52.185, Normal,Server,xldspntc02,,10.33.52.186, Normal,Server,xldspntcs01,,10.33.16.199, Normal,Server,xldspntcs01,10.33.16.198, On Mon, Mar 13, 2017 at 7:20 PM, Mike Peckar <fog(a)fognet.com> wrote: > Hey now, folks, > > > > This seemed like it should be simple, but I’m at wits end.

This seems to work: awk -F, '{linecount[$3]++;tmp=dup[$3];if(length(tmp)==0){dup[$3]=$0}else{dup[$3]=dup[$3]"\n"$0}} END {for (count in linecount){if(linecount[count]>1){print dup[count]}}}' Hopefully this is not a homework problem.

Hey now, folks, This seemed like it should be simple, but I’m at wits end. I simply want to find duplicates in the third column of a csv file, and output the duplicate line _and_ the original line that matched it.

Playing with Cinnamon last night I'm going to take the dive and throw it on a RHEL7 VM and see if I like it better than Mate. If so, I'll swap over my desktop and see...

(for meeting projectors) laptops,VGA-out,linux....
by Doug Mildram March 10, 2017

March 10, 2017

doug> Thanks Tim for bringing a functional laptop w/linux for last night's meeting. Our VGA-out projector worked fine as he installed a linux Mint VM (Mate Cinnamon) onto it. When that finished, I wanted to show/compare Mint Mate, which I had already on my laptop. When I unplugged Tim's laptop from VGA-out and tried my own thinkpad running Mint Mate (dualbooted, my alternate OS).....well,.....chirp. The projector stopped projecting. My Fn-F7 key seemed to be trying to cycle thru the blind toggles/choices (Duplicate display? screen-only? VGA-only might expect), but no video came out, I had to give up, not having tried VGA-out ever while running linux on my laptop. We put Tim's back onto VGA-out, and it also seemed dead, but we chose not to fight it, meeting being close enough to stop caring about projector, and it "wasnt a proud moment" for me. SO I WENT HOME and plugged my (same) laptop into my TV's VGA-in port. Started by booting win7. I'd never noticed a detail : at WHICH POINT does this start working....should I expect to see the dualboot/GRUB menu on TV? Apparently not. Soon enough though, Win7 (the OS preinstalled by Lenovo/thinkpad) came up and VGA-out/TV started working as usual. (somewhere AFTER "Resuming Windows", it starts working). To control VGA-out, Fn-F7 works ...I've got (4) choices: Duplicate, Extend(laptop-screen=#1, TV-VGAout=screen2), Projector Only (turns off laptop display), and Disconnect Projector (only laptop display ON). No doubt (i surmise), thanks to windows drivers. Feels like I learned: OS controls VGA-out (somehow naively I was inclined to believe this was more of an OS-independent hardware function). OK, now rebooted laptop/win7 to try Linux Mint from a win7 state with "Duplicate" working. "Shutting down Windows" displayed....laptop goes thru boot/BIOS?...TV is blank now, I've learned to expect this....Linux kernel boots, and I see some of the minimal console text messages as usual ALSO ON TV, laptop-screen AND TV quickly go to graphical mode, also displaying the Mate background... and this is where I was the most surprised. TV/VGA-out appeared "frozen' with the Mate background, appearing much like my laptop screen BUT MINUS anything else (no bottom launch/status/"panel" bar. Whatever I launch on my laptop screen, does not appear on VGA-out. Fascinating! Wed eve late, at my house, I could swear Fn-F7 still wasnt doing anything. But this Thurs AM, it DOES start working a bit (same 4 choices, but blind, and it's strange. TV/VGA-out doesnt show EVERYTHING). I wonder if I'd rebooted at the meeting, would that have helped, probably. Today I play with it some more (ALT-F2 helps when I'm in that semi-blind VGA-out situation, getting SOME things to show on TV) even though I'm not likely to use this feature much?ever? at home, unless I break a leg. Caveat, practice what you bring for meetings to project-OUT! HDMI is also an option in our WPI meeting/conf rms if you have it. ---trivia for Mate interest... (Mate = lightweight alternate to Cinnamon. Their start/launch menus are different, and I can find good stuff in Mate's Control Center. Cinnamon's Control center looks like this: https://docs.google.com/file/d/0B2V313X0LzmQclJCVkI5aFhIeDA/edit Couldnt find a good Mate comparison Control Center screenshot (not sharing some high-ad google'd choices) but I did like this decent page mostly cuz i love keyb shortcuts: http://securitronlinux.com/bejiitaswrath/some-useful-tips-for-the-linux-mat… where I learned CTL-ALT-d (lowercase "d" not DEL, which offers to reboot) .....lowers-or-raises what you're doing, a great "quick hide from over-shoulder" ninja move.

Reminder! Meeting TONIGHT March 9th, 2017! Topics: KVM, Virtualized windows apps, Linux Mint!
by Tim Keller March 9, 2017

March 9, 2017

Hey Gang, First the important details! Location: Rm 331 (Hagglund Room) @ 7PM Topic: read below... Tonight we've got a meeting! After the last meeting a couple of people were asking me questions about KVM (Kernel based Virtual Machine). New member Al Reinhart asked me a question about the best ways to run windows apps on linux, either via wine or through KVM / Oracle Virtual Box. He also mentioned Linux.Encoder (the first linux ransomware) which I didn't even know exists. Long time member Doug Mildram also wrote me about Linux Mint. A distribution I know quite well! They'll be some conversation and we'll kick off an install and talk about it's merits as a greate distribution. As usual, there'll be refreshments and snacks and afterwards we'll head to Tech for pizza! Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Tim, Another newbie request. Tomorrow night can you spend a few minutes talking about running Windows apps on Linux, i.e., Wine and virtual machines (my impression is VirtualBox seem to be the most popular). Last month the issue of ransomware came up and the consensus was there is none on Linux. In my wanderings around the web I came across Linux.Encoder as Linux ransomware: https://en.wikipedia.org/wiki/Linux.Encoder.1 Thanks, Al On 03/06/2017 08:55 PM, Tim Keller wrote: > Hey Gang, > > This is a reminder that we've got a meeting March 9th, 2017! > Location: Campus Center Rm 301 (Hagglund Room) > Topic: To Be Decided! > > Honestly, this meeting kind of crept up on me!
