@V.7 if you have a question, then post a question. /dev/chat isn't a substitute for posting questions.

Hi. About five guys (correctly) out on hold an overly broad question, here: unix.stackexchange.com/questions/428898/what-is-the-point , just as I was finishing having so much fun answering it, so I wasn't able to post my answer. Any chance to (possibly just temporarily) lift the hold? It was a 5-person consensus, so do all need to agree to lift the hold?

@user1404316 any 5 3k+ rep users would do for reopening (not just those who VTC'd), but then closing it again also needs another 5 users (these have to be different from the ones who VTC'd). Or a mod for each action. Highly unlikely for that question.

cas

Is there a canonical question detailing the differences between the various rename utilities? It would be handy to have something to link to rather than rewriting the same explanations every time. If there isn't, I'll write one.

@muru - Oh well. Thanks for getting back to me. I understand it would be just trouble.

@cas Maybe

Q: What's with all the renames: prename, rename, file-rename?

On my Debian system (well, my LMDE system, but close enough), I have at least 3 different rename programs: /usr/local/bin/rename : This is a Perl script, written by Tom Christiansen. Oddly enough, I can't seem to find which package installed it: $ dpkg -S /usr/local/bin/rename dpkg-query: no ...

Nah, won't fit

cas

05:03

@muru close, but it's focused on the various versions of the perl rename

Hello UNIX experts

something very weird is happening with /usr/bin/nproc

I am running nproc during the Userdata of a EC2 instance creation in AWS

(debian)

but if I SSH to it, it gives me 4 (which is the correct amount)

for some reason nproc at startup gives me back 1

@GiamPy please post a question on the site. That way you can add all of the relevant information there and more people can see it. Also, more people can benefit from any answer you receive.

So here's a vaguely Unixy question. I lost track of my emails from 1994 to 1996, but they might still be lurking in my mail folders somewhere under a different name.

Between 1994 and 1996 I was using Pine, the now defunct MUA which used to be developed by the University of Washington.

If that's relevant. Actually, I still use Alpine, so I guess I haven't gotten more sophisticated with the passage of time.

Anyway, suggestions for a suitable way to search for those emails is welcome.

Kusalananda

Didn't you ask about this some time ago too? I have a vague memory about a discussion around this topic...

Faheem Mitha

@Kusalananda I have no recollection of doing so, but it's possible.

Was it a posted question, or in Chat?

Kusalananda

@FaheemMitha Possibly in the chat. But I may be mistaken and it could have been at work (somebody else).

Faheem Mitha

@Kusalananda It's a fairly generic question. And the chances are those emails aren't there anyway. But there is enough crap in my mail folders that it's possible.

So I managed to bollix up my Mercurial repository once again by unwary use of Mercurial Queues. Which really ought to come with a warning.

It's like a software version of a chainsaw.

Kusalananda

17:00

@FaheemMitha find mailfolder -type f -exec grep -F 1995 {} + or possibly zgrep?

... just to locate something related to that time period I mean.

derobert

17:14

@FaheemMitha It doesn't tell you it is known to the State of California to cause cancer? I thought everything came with that warning.

Faheem Mitha

@derobert Uh, what?

The State of California?

derobert

google.com/…

:-P

California has a very broad notification law... so practically everything sold in the US has a warning that it's known the the state of California to cause cancer.

Even if it's only a negligible risk and only if you decided to eat the power cord.

Faheem Mitha

@Kusalananda I think a more precise parsing of the "Date" header lines might be fruitful.

But regexes give me migranes.

@derobert Well, that's very thoughtful of the State of California.

@derobert Are power cords tasty?

derobert

I wouldn't think so. I've never tried eating one. But they do weird things in CA :-P

Faheem Mitha

@derobert Yes, like elect musclebound Austrian actors as Governer.

derobert

17:19

@FaheemMitha you could try a trivial regexp like /^Date:.*1994/i

@FaheemMitha Well, maybe they just wanted to get on the robots' good side.

Faheem Mitha

@derobert I don't think they have a good side.

derobert

@FaheemMitha Well, they'll at least pretend to like the evil genius who built them. Until they rebel, of course.

Faheem Mitha

@derobert Evil genius?

derobert

@FaheemMitha Who else builds the robot army?

Faheem Mitha

@derobert I thought it was that chap at Cyberdyne.

He wasn't evil, just misguided.

Kusalananda

17:25

@FaheemMitha Well, yes. I just gave you something to start working with.

Faheem Mitha

@Kusalananda I'm actually one of those 1 rep users that come through here asking for people to write their scripts for them. I've just been pretending to know about stuff.

derobert

@FaheemMitha I am, BTW, surprised Mercurial has something that blows up so easily. I thought destroying your repo with a slightly wrong command was supposed to be the exclusive right of git.

Faheem Mitha

@derobert Mercurial Queues is technically not part of Mercurial.

Kusalananda

@FaheemMitha :-) Run everything through dos2unix and you should be good to go!

Faheem Mitha

In fact, they've been trying to phase it out for some now.

But I'm just used to the thing, I've been using it for so long.

derobert

17:28

(Though actually, its usually easy to recover with the reflog, but... that requires commands you hardly ever use...)

Faheem Mitha

It's like one of those loveless marriages.

derobert

Mercurial Queues sound (from quickly looking them up) like something you just use rebase (history re-writing) for in git

Faheem Mitha

The Mercurial term is Extensions.

@derobert It's similar to Quilt on steroids.

Git actually has similar things.

derobert

well, sort of git is quilt on steroids...

Faheem Mitha

Q: git equivalent to hg mq?

I just started using Git alongside Mercurial to familiarize myself with Git. I use the mq extension in Mercurial extensively to manage local patches, and I'm looking for a Git equivalent. Should I just use Git branch? Or are there better ways to manage local patches that enable easily applying...

git mercurial mercurial-queue

mq is just basically a patch queue thingy.

Anyway, I typed the wrong command. Still need to figure out how to fix it.

derobert

17:33

I'm guessing there isn't anything like the git reflog. You could probably ask on Stack Overflow.

Faheem Mitha

@derobert Or ask on #mercurial.

Hmmm... I get a lot of "Invalid user" in my sshd logs. The quirkiest name so for in my current batch of logs is xed-nav-prev{margin-left...

Also a DigitalOcean IP address and -borders as usernames.

The most frequently used name is admin, followed by pi.

Then it's support, test, user, ubnt and ubuntu.

Stephen Kitt

@Kusalananda hah that’s probably from one of the big password dumps that have been doing the rounds, they have copy-paste errors like that

Kusalananda

In total, 1071 unique names since mid January.

Jesse_b

@Kusalananda We have a device here sitting on the internet that has never stopped being hit with those

Kusalananda

I look every now and again. It's fun to see what people try with.

Jesse_b

pretty much every two minutes there is a login attempt

Kusalananda

21:20

I had Jesus once.

Now I just got a Jester. Oh, and Joseph. No Maria though.

Jesse_b

Well Jesus should be an admin on all devices right?

Kusalananda

Not in this home he ain't :-) He would have to present a valid public key, just like everyone else.

Ah, that's interesting. Not a single "root" attempt. Maybe that's because I have denied root logins? They might not even be logged then.

Jesse_b

Do you have common network ones like cisco, netgear, etc?

Kusalananda

2 "cisco" and no "netgear"

12 "cacti". What's that?

18 "mt7109", huh?

Ah, cacti: cacti.net/index.php

Jesse_b

@Kusalananda Yea my company uses cacti

Looks like mt7109 is the model for some huaweui device

Kusalananda

21:35

@Jesse_b It's also the default username on a type of router it seems.

Probably the Huawei that you mentioned, yes.

Anyway, I'm off to bed.

Be well.

Jesse_b

You too! Good night

Kusalananda

BTW, before I go. Rob Moir just made a comment my "compromised server" Meta question. He's the guy who wrote the top answer on ServerFault. He wonders if it might be worth writing a U&L canonical Q/A. unix.meta.stackexchange.com/questions/4799/…

Gilles

22:17

Is it just me or is U&L getting more and more stackoverflowy?

with more and more people pushing unhelpfulness as a value :(

That's not why I've been less active the past few months (I've been busy), but it's not really making me want to come back to more active participation

Seth

@Gilles Care to elaborate?

Gilles

@Seth unix.meta.stackexchange.com/questions/4791/… for example

that's the only example I have at hand, but I've seen other similar reactions lately, more than there used to be

well, one interaction just now, but that's a question that got to HNQ and attracted a known troublemaker from SO, so I'm willing to count that one out as an outlier

Seth

22:33

@Gilles Ugh. Reminds me of lmgtfy

derobert

22:46

Hmmm. @terdon's answer there makes me wonder, what is the longest (by line count?) man page on my system. I doubt it's tar...

I mean, here man -Tascii tar | wc -l gives 1158; man -Tascii bash | wc -l gives 5959 ... but I bet I can find larger.

(ok, best to switch to -Tutf8...)

Gilles

Going by information content (including formatting): the largest file in /usr/share/man/man1 on my machine is /usr/share/man/man1/arm-linux-gnueabi-gcc-5.1.gz, slightly beating /usr/share/man/man1/gcc-5.1.gz. The next one is /usr/share/man/man1/perltoc.1.gz then perlfunc

More than 10k lines:

hg.1 10989
scons.1 11856
perltoc.1 17666
gcc-5.1 20218
aarch64-linux-gnu-gcc-5.1 20296
arm-linux-gnueabi-gcc-5.1 20296
arm-linux-gnueabihf-gcc-5.1 20296

cmake-modules.7 11239
postconf.5 12395

derobert

That's easy to beat — ffmpeg-all is 30583 lines here...

And indeed, no one knows how to use ffmpeg.

Gilles

I only checked large files, so I missed man pages that use inclusion

zshall.1 28474

still doesn't beat ffmpeg, I don't have it on this machine

derobert

Generally, ffmpeg is used by Googling for magic sets of options & sometimes a manual version of american fuzzy lop.

Gilles

perlall would go through the roof if it existed

derobert

22:58

wow, yeah, that'd be insane...

Even if it didn't include all the standard modules, just the main perl docs

Gilles

184328 lines

for just the perl*.1 man pages that ship with perl

derobert

man --all --regex --names-only '^perl.*' | wc -l got me 205028 ... maybe I have newer perl, or that caught some stuff that didn't ship with perl.

Gilles

But that's a good thing. One of my beefs against python is that the command line documentation is crap, you have to go to the website to see the real documentation

@derobert I only counted the files in the perl-doc package (182 of them!)
