@Kiwy you could do that with GNU cut, sort, and uniq. e.g. cut -d ';' -f2,3 --output-delimiter=$'\t' input.csv | sort | uniq -c. Without GNU cut, you could use sed between cut and sort to change the semi-colons to tabs - cut -d ';' -f2,3 input.csv | sed -e 's/;/\t/g' | sort | uniq -c

@cas Yes that I know and I use cut | uniq | sort a lot already, my goal is to try to limit cpu usage and try not to read a 6GB csv 4 times because it's taking too much time

:P

Stephen Kitt

@terdon LOL

trust you to write a good answer just before I catch up with you

Kiwy

you're a child @terdon

:D

terdon

@StephenKitt Bah, just regurgitating standard info.

Stephen Kitt

I like my edit comment better though, because “Tab. Where no one hears you scream” doesn’t work quite as well

terdon

@Kiwy :P

@StephenKitt heh

It also kinda bugs me that there's a tab there, to be honest, even if nobody can actually see it.

But that's my penance for childish jokes.

Let's see how long it takes for you to go back and remove it ;-).

Kiwy

and after that you are doing moral to poor user who do not put a complete nice documented answer while he actually answer the question :D

Hello chat how can I invtie someone in chat if doesnt have a profile

terdon

@Kiwy You can't, I'm afraid. They also need 20 network rep to chat anyway.

Kiwy

@terdon ho you can't invite someone in private room to discuss so I need to continue talking by comment with someone whop obsviously have a solvable problem but can't understand his question...

too bad :-(

terdon

@Kiwy The system will create their account automatically as soon as you get the "continue in chat" message.

But I can do it too, mods can do this. Who is it?

Kiwy

Ho so I should continue spamming comment, what a nice workflow

that guy

delfiler

i just want to invite him to private room to discuss his question Because I'm pretty sure he just don't know how to ask it

terdon

@Kiwy OK, done

Kiwy

11:26 AM

@terdon so now he can connect to chat ?

Thank you very much

terdon

@Kiwy Yes, and you're welcome :)

Kiwy

12:48 PM

@Terdon now I think the question is a bit more understandable and clean

Q: Identify matching rules in iptables to validate configuration

I have set up lot's of rules on iptables (if you want the orignal script click here : iptables -A INPUT -m set --match-set banned src -j DROP iptables -A INPUT -m set --match-set whitelist src -j ACCEPT iptables -A INPUT -m set --match-set whitelist2 src -j ACCEPT iptables -A OUTPUT -m set --ma...

iptables

Feel free to vote reopen, though I feel like it will be close as duplicate

terdon

Um. That microsoft link thing doesn't work for me. And, seriously, "word online"!? for a script!?

Does this make sense?

we have an application running on it (OTRS) and it became slow in responding but it turned out that the LDAP Server used for lookups was unavailable - after correcting it, the application started to behave normal but their support claims that we should have 60% free space in swap but sa you mentioned, when the system decides itself when to swap how can we even control it ? — yesOrMaybeWhatever 29 mins ago

Why would you need to have a specific % of swap free?

Kiwy

1:55 PM

@terdon very odd

I installed Debian on a desktop computer just for testing and came across nearly 22 stages of installation, unlike Ubuntu / Windows 10 that each has 3-4 steps at most.

Why does installing Debian is so long by means of stages?

Do you consider it a UX problem?

Kiwy

no it's not a problem debian installation is precise and let the user decide precisely. that's an intended behavior to me and a one I like so much

This one’s weird:

Q: Rsync for migrating very large nfs share

I wanted to get input on how to break up an rsync task into multiple parts to make the change log accrual go faster. The situation is we are migrating off of one storage platform to a new storage platform. We have one large flat directory with 2.5mm files inside it. the rsync change log curren...

one of the answers there was reviewed as NAA, recommended for deletion

@StephenKitt I've flagged it again.

Stephen Kitt

@Kusalananda Thanks!

It looks like a mod actually converted the answer to a comment, but didn’t delete the answer somehow.

user9303970

Is there a "common" way to install Debian desktop aimed for people who would wish not to go through all the stages?

terdon

Yes, it's called installing Ubuntu instead :P

Stephen Kitt

@terdon oooh that burns

Kiwy

well there is a grpahical installer like ubuntu I think you need to have the DVD or on a USB key and boot as live debian

@terdon you're full of fun today :P Ubuntu is great and Debian as well

Archemar

3:22 PM

On the other hand, ubuntu with many option is called Kali Linux ?

terdon

@StephenKitt It's basically true though. if the many steps in the Debian installer seem too much (which is a perfectly understandable position), then you probably don't want Debian and would be better off with a more user-oriented distribution instead.

@Kiwy I didn't mean to imply the opposite. Just that they have slightly different target audiences.

So if you see many options in an installer and think "Yay! Choices! I can do it the way I want", then go for Debian. If instead you think "Man, why do I need to decide about very little thing!" go for Ubuntu.

Both reactions are perfectly reasonable. Just different people.

@Archemar Eeeek! The K-word!

:P

And no, Kali's based on Debian, not Ubuntu.

Stephen Kitt

@terdon yes, you’re right

and if you want Debian without a lot of installation steps, you can automate the installer, but that’s not for beginners

@Archemar Kali is Debian where if you get things wrong, you go to jail^W^W^W^Wapt upgrade stops working

user9303970

Terdon I use Ubuntu for a few years now but I would really wish a more minimal (in installation as well) usage of the Debian ecosystem.

Archemar

wow one year and an half to accept question !! unix.stackexchange.com/questions/293960/understanding-unix-user/…

user9303970

@StephenKitt is there a version that comes automized out of box instead I go and automize the setup manually?

Stephen Kitt

3:37 PM

@user9303970 bare-metal, or VM?

user9303970

I assume - bare metal, as it is being used in my PC.

But to test I might first go on VM.

Stephen Kitt

for VM use there are simple setups, e.g. for use with Vagrant

nothing for BM AFAIK

I mean, nothing pre-build for BM

the thing to look for is FAI, fully-automated installer

user9303970

BM?

And thanks, I'll look for a Debian FAI.

Kusalananda

@user9303970 "Bare Metal" The actual machine.

derobert

@user9303970 errr, don't pick expert install if you don't want so many questions?

Kusalananda

3:44 PM

Hmm.... There is no music group called "Bare Metal"? Boring...

derobert

So, Debian Installer asks me (when I don't do expert install) for locale; hostname; password; disk to install on; partitioning; if I want to participate in popcon; and then which broad groups of software to install. That doesn't seem like much more than a Windows install asks for...

And some of that is because Windows just presumes answers (e.g., d-i asks you about popcon, Windows would just enroll you...)

And honestly... most of those d-i questions you can just hit enter on... they have reasonable defaults. At least they did on the VM I just tried it on.

Stephen Kitt

4:00 PM

@derobert yeah, like the “spacebar installers” pioneered by Borland (I think) in the early Windows 3 days

user9303970

4:29 PM

@derobert I don't recall these were only "You could just hit enter" sort of questions.

I might have did a mistake picking "expert" install because I didn't think what Mr trovalds said in 2006 or 2008 (about I guess his try to install Debian in about 2005) would be relevant in 2018, I mean, I heard a woman in the audience saying the installation is very simple "now".

I personally have enough by locale, partitions, etc. That's what I configured both in Win10 and Ubuntu.

derobert

@user9303970 I personally seldom use expert install. Unless I need to do something weird...

Mostly expert install just makes it ask pointless questions.

user9303970

The heading is bad:

Why Linus Torvalds doesn't use Ubuntu or Debian

►

I was mistaken, He did say a similar saying in about 2007 but the video I talked about is likely to be taken in 2014. Anyway, next time I install Debian, I'll ensure not pick "expert" install option so indeed I'll basically just have to set locale, partitions until the installation process ends.

Videonauth

well whatever linus does use, he has for sure always the latest kernel ...

derobert

4:53 PM

@user9303970 Indeed. That option really ought to be labeled "experts dealing with weird $*#@($-up situations", but I suppose that wouldn't fly...

And yes, I totally want to run an amiga partition table on this machine! (Or whatever dozen options it offers you...)
