@Alvar wow, someone is recommending Kubuntu as a light system?

RPi Awesomeness

Whoa...they obviously know like...nothing about Ubuntu/derivatives

here the reason why we need audits

@iKlsR seems like the new thingy that they branched of nautilus

iKlsR

@Braiam Does this thingy have a name?

Braiam

@iKlsR Ubuntu Filemanager app

iKlsR

Hmm, I was mostly attracted to the flat look and edges, wonder if that can be customized, the edges.

Thanks.

Seth

1:39 AM

Hmm.

RPi Awesomeness

hmmm what?

Seth

@iKlsR Something like this? omgubuntu.co.uk/2014/01/iris-flat-gtk-theme-for-linux

terdon

@Seth this sounds reasonable, should I delete my Q then?

@terdon This bug is at the point where it can be reported, and you're reporting it on AU to do troubleshooting that should be done on Launchpad. I don't see how this question is in any way different from all the other questions where people ask for help with crash bugs, which we regularly close as off-topic. If I retract my close vote, I will not be able to vote to close this question again (that's how the system works). Since the main issue at hand when voting to close a question is whether or not it should be closed, I think the best thing for me to do is leave my close vote as it is. — Eliah Kagan 2 mins ago

RPi Awesomeness

That ... looks... interesting

Seth

@terdon Don't delete no, but I can close if you'd like.

You should try installing Gnome and see if it crashes.

Deleting a question for no good reason is a no no.

terdon

1:43 AM

@Seth I'm betting it won't this really looks like a compiz issue.

@Seth OK. BUt he's right in that this kind of thing is off topic then?

Seth

iirc gnome uses compiz too.

terdon

@Seth Oh, I thought they didn't and the compositing was done by the shell. I know that's how cinnamon does it.

Seth

@terdon Yes, that's our current policy. I'm a bit busy atm, but I'll try to explain more later.

@terdon yes

terdon

@Seth Don't worry about it, reading the relevant meta posts now. Just trying to figure out where you draw the line :)

iKlsR

2:16 AM

@Seth I think that's it. Thanks.

Braiam

@Seth gnome ditched compiz a long time ago, it uses metacity/mutter for everything else

DK Bose

Is this comment 100% correct? askubuntu.com/questions/210976/…

Seth

2:39 AM

@Braiam Are you sure? What's the difference between Gnome and Gnome no-effects then?

@DKBose I believe it is.

@terdon Okay then :)

DK Bose

@Seth does "When you type sudo apt-get remove -s k3b*, bash will first look for any files in your current directory that begin with k3b." look correct?

Seth

@DKBose I'm not entirely sure, but I suppose it's true..

Lemme see if I can look it up.

DK Bose

@Seh, my understanding is that neither remove nor purge will touch files in /home/user/

touch means delete not command touch. Sorry.

Seth

I can't seem to find any references..

@Braiam Know anything about this --^ ?

Braiam

@Seth err... yeah, I don't have compiz, and I'm using mutter ;)

terdon

2:46 AM

@DKBose Yes it's true, whenever you have an unquoted glob pattern, the shell will expand it before it passes it to whatever command you are calling

Seth

@Braiam Huh, so what's the difference between gnome and no effects?

Braiam

@Seth "no effects"?

Seth

@Braiam gnome-flashback and gnome-flashback-no-effects mainly.

Braiam

I don't have gnome-flashback-no-effects... do you know about it @terdon?

terdon

No, sounds like Ubuntu specific stuff. As far as I know everyone has ditched compiz except unity

DK Bose

2:48 AM

@terdon, thanks so that means if I have a file called k3b.txt in my home, running sudo apt-get remove k3b* will "remove" it? I will test that with a longer string.

terdon

Ah, perhaps not LDE but all of the Gnome derivs

@DKBose no, it will run apt-get remove k3b.txt instead of apt-get remove k3b*

DK Bose

@terdon But apt-get doesn't delete files in /home?

terdon

@DKBose no, not unless they were installed by one of the removed packages

Braiam

not even if some package install some, is a violation of the debian policy

terdon

But the comment you linked to is not saying that the files will be removed

Seth

2:50 AM

@terdon Is installed the same as created or is it different?

I mean, apt never removes config files in ~

Braiam

normally they are created by the program at launch

terdon

@Seth it will with purge won't it? It should delete the whole ~/.config/foo tree as well

Braiam

or if they are in the skel directory

@terdon nope, it wont

terdon

@Braiam in that case, they just get copied over when you create a new user

DK Bose

Purge doesn't affect ~

terdon

2:51 AM

@Braiam OK, wasn't sure about that one.

The issue about k3b* has nothing to do with apt though, it's pure shell

Braiam

dpkg -S /home/braiam
dpkg-query: no path found matching pattern /home/braiam

DK Bose

Neither purge or remove affect files in ~

terdon

OK

DK Bose

The context is the question which is apt-get.

terdon

@DKBose yes. But the problem is because of the unquoted pattern, it happens before apt-get is called

DK Bose

2:53 AM

And is 'remove' a Bash command per se?

Braiam

yeah, but the question ignores the shell which is the one that manages unquoted globs

Seth

@terdon nope. neither remove nor purge touch config files in /home

Braiam

@DKBose no, anything after apt-get is an apt-get command

terdon

@DKBose no, again. What happens if you have a file called k3b.txt and you run apt-get remove k3b* is that what you actually run is apt-get remove k3b.txt instead. That will not delete any files but it will also not do what you want

Braiam

@DKBose use echo sudo apt-get remove k3b* and see

Seth

2:54 AM

@DKBose no no, but bash interprets k3b* before it passes it to apt.

Braiam

apt-get can't remove a file directly anyways, only removes packages

DK Bose

Now my head is spinning. I will look once again and get back. But I still think that comment is not 100% correct -- my original point ;)

terdon

@DKBose It isn't, but because k3b* is not actually a regular expression :)

Well, it's not interpreted as one by apt anyway

The regex would be k3b.*

Braiam

@terdon that's a greedy one ;)

terdon

@Braiam Actually, I'm reading the man page and they say it's a POSIX regex but then, they don't respect the syntax!

Avinash Raj

3:00 AM

i downvoted 4 answers.Does the answers can be able to see my reputation loss due to downvoting.?

terdon

@AvinashRaj Why do you care? If they deserved the downvote, you did the right thing.

Avinash Raj

DUPE askubuntu.com/questions/344210/…

Seth

@AvinashRaj You mean the answerers? No.

Avinash Raj

yes

Seth

Then no.

Braiam

3:03 AM

@AvinashRaj nope

Avinash Raj

so that they can easily identify "oh he is the culprit who downvoted me.I'm going to take revenge for this"

Braiam

@AvinashRaj unless you disclose who you did downvote, no, nobody knows, not even mods

terdon

This is fun. @Braiam try apt-cache search --names-only kde* | grep tkcv

Then try apt-cache search --names-only kde.* | grep tkcv and tell me why that one doesn't match.

For that matter, why does the first one match?

Braiam

I have no freaking idea...

Avinash Raj

@terdon echo "Good Morning $(cat ~/Desktop/file.txt)"

in the above code,the contents of file.txt are continuously displayed along with Good Morning

Good Morning

contents of file.txt

what i have to do to display like

Braiam

3:08 AM

ok, I think I have something @terdon, kde* looks for any package containing the letters k or d or e, which is morronic

when you use .* it returns something you would expect

terdon

@Braiam So you think it treats it as [kde]? Even so,. that would be [kde]* which matches everything

@AvinashRaj like? And there shouldn't be a newline there unless you have a blank line as the 1st line of your file.

mm... wait...

/n

\n

then I have no idea how it match tkcvs

Avinash Raj

3:11 AM

plz rewrite the code for me

Braiam

heh, look at this:

Avinash Raj

> echo "Good Morning \n $(cat ~/Desktop/file.txt)"

Braiam

➜  ~  apt-cache search --names-only 'kd' | wc -l
462
➜  ~  apt-cache search --names-only 'kde' | wc -l
344
➜  ~  apt-cache search --names-only 'kde*' | wc -l
462

Avinash Raj

is this correct?

Braiam

I still have no idea why kd matches tkcvs

Seth

3:14 AM

@terdon Per Shog9's cough encouragement cough I've shortened up the help page a bit (removed the <ul>). Just a heads up.

Braiam

and found the reason @terdon

apt-cache show tkcvs | grep -i kd
Replaces: tkdiff
Provides: tkdiff

terdon

@Seth fair enough. Thanks for letting me know but I'm just the newbie who posted the meta Q. You're a mod and a high rep user, I really don't think you need my approval :) Anyway, you have it for what it's worth, as long as everything is listed I am content.

@Braiam OK, good start but I'm using --names-only, shouldn't that match the package name only?

Braiam

so summary: apt-cache search abc* only matches ab and eats up c and *

@terdon those are packages names that it replaces/provides

terdon

@Braiam not quite, that's fair enough, abc means match ab followed by ) or more c so ab is a valid match

Braiam

I presume they are doing a favor in case some packages changed names or something

terdon

3:17 AM

@Braiam Huh? I thought --name-only simply searched the list of available package names, not their descriptions or meta data

Braiam

> Only search on the package names, not the long descriptions.

I presume the Provides is also a package name...

aptitude thinks so too...

Seth

@terdon Just fyi :)

I respect your knowledge and opinion.

terdon

@Seth awww shucks! Right back atcha!

:)

Braiam

the thing is a virtual package...

terdon

@Braiam yes, I can see how one might think so :). Still, I want to be told about available packages not the ones they might replace

Braiam

3:23 AM

@terdon do apt-get -s install tkdiff and lets see ;)

terdon

@AvinashRaj what is the format you want to see?

@Braiam heh, not even it searches through every package name in the description I think:

$ apt-cache show tk8.5-doc | grep -i kd
Provides: tkdoc
Conflicts: tk8.3-doc, tk8.4-doc, tkdoc

Braiam

yep, now the thing is... does apt-get action kde* interprets the same as apt-cache --names-only kde*

yep: Remv libkdb5-7 [1.12+dfsg-2]

terdon

@Braiam that's OK, as it should be, the regex is matched as a substring (that's documented) and kde* matches kd so it should bring libkdb5

Avinash Raj

@terdon

i got it

> echo -e "Good Morning\n$(cat ~/Desktop/awk)"

Braiam

now, there was a Q about why package* removed so many packages...

terdon

3:27 AM

On the bright side, apt-get install 'kde*' does not match tk8.5-doc

Seth

LOL

terdon

@AvinashRaj OK, I though you wanted to avoid having a newline. To be on the safe side, never echo the contents of files like that, you could get surprises. Use printf instead: printf "Good Moring\n%s\n" "$(cat ~/Desktop/awk)"

@Seth you laugh but apt-cache search --names-only 'kde*' does match it!

Seth

Yeah, it's weird.

Avinash Raj

these are neeeded for my new script.It may be released today :-)

terdon

@Seth As @Braiam discovered, is seems to match more than the packages, in this case it's cause it provides tkdoc or because it conflicts with tkdoc. Ain't apt grand? Apparently tk8.5-doc does both :)

@AvinashRaj If you're releasing a script, you should seriously consider using printf instead of echo, see here for more details than you ever wanted to know,

Avinash Raj

3:35 AM

thanks for letting me know @terdon

bash command to check the presence of file contents(file contains any text or not)

terdon

@AvinashRaj [ -s foo ] || echo "file is empty"

[ -s foo ] && echo "file is not empty"

Avinash Raj

ok thanks

terdon

3:51 AM

Is there a "magic command" to restart unity? One that doesn't need access to a terminal, just a shortcut, like Ctrl+Alt+Bksp but for unity?

Seth

sudo lightdm restart or unity --replace.

Note that if you're in a tty you'll have to set $DISPLAY

terdon

@Seth yeah, they need a terminal. I just want a quick way of restarting unity or compiz on my VM when it dies. At that point, unless I have a terminal open, I'm screwed. I can't seem to insert a Ctrl+Alt+Fkey to drop to a tty and can't do anything graphically.

Seth

Ah, maybe you meant "Doesn't need access to a terminal"?

terdon

Cinnamon used to have a shortcut (admittedly cause it crashed often) but no longer (probably cause it's more stable). I was just wondering if there was such a thing out of the box for UNity

Seth

Might have to tinker with Virtualbox settings to make sure key combinations are sent properly.

terdon

3:55 AM

@Seth maybe, yeah ;) Sorry.

Seth

fixed ;)

terdon

@Seth Good idea, I'll have a look. I think I'm solving it though and it's not a bug.

@Seth Oy! You guys can do that? Tsk.

Seth

@terdon It's probably still a bug (i.e. this shouldn't be happening), but that's great!

terdon

Can you do that on all chat rooms or only those of the site you mod?

Seth

@terdon And a whole lot more scary stuff ;)

@terdon All of them, except SO and MSO rooms

You're a mod SE chat wide.

terdon

3:57 AM

Drunk on power... :P

Seth

lol. The really powerful stuff requires going to your profile, no one really looks at those unless they need to. Still, that's why mods need to be highly trusted users ;)

Hm, I wonder if there's an ikea.se site.

Braiam

@Seth just for the lolz?

Seth

@Braiam partly, but I have a question I'd like to ask right now :P

Braiam

facepalm

Seth

IKR :P

talk about keeping a 2 year old busy.

terdon

4:01 AM

@Seth If you think something like that is only fun for a 2 year old, you should give up your geek badge now.

Seth

@terdon lol. I meant, young kids would sit around that for hours just watching it go 'round and round.

terdon

@Seth I know what you mean: "If I tell the wife it's for the kid, she'll let me buy it! Whohooo!"

Seth

@terdon ROTFL

terdon

:)

Seth

They so need to integrate that into Unity. You know how many times I've tried to do that?

Seth

4:31 AM

Ubuntu doesn't have any built in fingerprint reading capability does it?

terdon

Yay! I think I fixed my Ubuntu VM. And it's not a bug, just had to install things I hadn't.

Seth

Like what? Written an answer?

Technically, you should have to install something for it to work..

terdon

@Seth I don't know but see these links, it seems straightforward enough: thinkwiki.org/wiki/…

@Seth Not yet, will do. I meant I needed to 1) install the Vbox extension pack 2) install kernel headers and build essentials on the guest 3) compile some modules (done automatically) 4) insert said modules.

Avinash Raj

1st vote by me

Seth

@terdon afaik non of those support my reader :(

That isn't my question however.

@terdon Hmm.

terdon

4:36 AM

@Seth I was thinking it might be cause of this: launchpad.net/~fingerprint/+archive/fingerprint-gui

Seth

I have the 138a:003c :(

terdon

@Seth I tried playing with the one I had on my thinkpad but it never worked that well and was not worth the trouble (I used it when logging in to Windows mind you)

Brilliant. I've come full circle. I found a French blog site explaining how to fix my VM issue and it turns out they were quoting (and correctly referencing) this:

190

A: Why does a Ubuntu 12.10 guest in VirtualBox run very, very slowly?

Ubuntu 12.10 no longer includes Unity 2D, which was implemented for platforms that can't provide 3D acceleration. Instead, Ubuntu 12.10 has Unity run under LLVM, making code intended for the GPU run on the CPU. It is much slower than using the GPU. To check if your Ubuntu 12.10 guest is using 3D...

Seth

@terdon They're fun, but they don't work with the Windows 8 login screen yet nor Ubuntu well either :(

terdon

@Seth think you could close my question as a dupe of that one?

Seth

If you'd like, sure.

terdon

4:40 AM

@Seth Not even win8? Weird.

@Seth Well, that is the exact solution I followed so...

Seth

@terdon The software works in Windows 8, just not the login screen.

terdon

lol, how useless is that?

Seth

@terdon Alrighty then. Could you add a comment?

@terdon Well you can use it to log into websites and stuff like that. (it's HP software).

It worked on the Windows 7 login screen. Guess MS changed a lot in the Win 8 one.

terdon

@EliahKagan you make a good point and thanks for explaining. Turns out it was not a bug but it is a dupe! Following the solution suggested here fixed it. So please, let's close it as a dupe of that one instead. — terdon 14 secs ago

I answered Eliah since he was nice enough to explain the bug stuff to me. And seriously? Log into websites with a finger print reader? Wow. People really prefer high tech over safe.

Seth

@terdon ikr

and done. Sorry about all the wrong close votes. We get a lot of that 'round here :-/

Which is why we now have review audits, but still.

terdon

4:45 AM

@Seth as far as I know (don't have the rep) there was only one from Eliah and and that one in good faith so no problems here :)

Seth

@terdon You got 3 more, two to the dupe and one to the OT

terdon

Oh well. :)

Seth

Yep :-/

I think that screenshot you gave helped some of them along, matches the one in the dupe post.

@terdon btw, you have enough rep to view the close votes on your own questions ;)

\o @Mitch. Guess you arrived as my replacement for the next watch? ;P

Alvar

9:34 AM

I've found a bug with my wireless how do I report it?

guess it's ubuntu-bug somePackage, but what package can it be?

Oli

@Alvar Find the driver module, find the files related to that module and then you can dpkg -S /that/path to get the package.

Alvar

the bug is that whenever I disable the wireless (click on the wireless icon and disable) when I then hit enable nothing happens. Or even sometimes it says disabled by hardware switch when I disabled by software switch

also the hardware switch doesn't work. I have to boot up Windows to get it working. Where the hardware switch works

Oli

Yeah, these sound like legitimate grievances... It's most likely a Kernel bug (that's where most of the drivers live) and to properly test that (enough that upstream likes it) you'll need to grab and build the very latest version of the kernel and confirm things are the same. If they've already fixed it, you might have the option of just using a later-than-Ubuntu-uses Kernel.

Alvar

uuuuurgh

Oli

But confirm it's a ships-with-Kernel driver first. It might be something else.

Alvar

I tried that once, it's sooo much work

how do I confirm it?

Alvar

off topic, shopping recommendation askubuntu.com/q/432147/10698

ls /sys/class/net/wlan0/device/driver/module/drivers
pci:rtl8192se

Oli

And then modprobe -nv rtl8192se should give you paths

Alvar

it outputs nothing

Oli

Might be because it's already loaded. If you can afford to disconnect you could sudo modprobe -r rtl8192se first to unload it.

Alvar

ooo 12 more reviews then I'll reach steward on close votes...

I'm using wired network and no it doesn't have to active right now

Oli

Snap. Sorry I didn't think of that earlier.

Alvar

that you could do it?

Oli

Yeah. I was too much in "teach-to-fish"-mode... It's part of linux-image-extra-3.11.0-18-generic so yeah, you'll want to test out a couple of different kernels before you report anything first.

Alvar

9:58 AM

uuurgh, that means I have to test beta nvidia drivers as well or nothing will work on the computer...

Oli

That is true. In fact, I can't even get the latest beta to work on the very latest Trusty kernel.

Alvar

another reason I wont try this, it's too much work..

the annoying part of reporting bugs, testing :(

Oli

You could download a daily and just use Nouveau in a live session to test the wireless

Alvar

true

that's quite clever

and very easy

booting up windows to fix the wireless in Ubuntu -_-

Oli

Somewhat less permanent and you'll then have the option to test older (but newer than 3.11) kernels without the nvidia module refusing to build

Alvar

10:01 AM

and it is less work

Oli

True enough. At the other end of the spectrum to your initial question, you could rip out the existing wireless card and replace it with something known to work well. mpci wifi cards are pretty simple to replace and they're not expensive. Getting access to them inside the computer can be education too.

Alvar

it's a netbook I use for coding and it's 3 years old I wont do any more upgrades on it.

last few kernels has been stable and before that there were freeze bugs. But it will work better on the next kernel

awk ' ( /W:/ && /www.launchpad.net/ ){print $5}'

but the command executes successfully

When i give search pattern as

( /W:/ && /launchpad/ )

it won't show awk: 1: unexpected character '.' error

terdon

Both of those should work

i don't know

terdon

My point was that the parentheses are needed for more complex statements.

Avinash Raj

i think there was a problem in giving . in search pattern

terdon

echo "aa bb" | awk '(/a/ && /b/)'

echo "aa bb" | awk '/a/ && /b/'

both work

Avinash Raj

@terdon i tried that also

when i give ( /W:/ && /www.launchpad.net/ )

it shows the error

it won't

( /W:/ && /launchpad/ )

terdon

echo "WW: www.launchpad.net 3 4 5" | awk ' ( /W:/ && /www.launchpad.net/ ){print $5}'

The only problem with giving . is that it matches any character, not just .

so what i have to do.

not to get

terdon

@AvinashRaj What is the exact command you are running?

Avinash Raj

awk '( /W:/ && /www.launchpad.net/ ) { print substr($5,26) }' file.txt

terdon

@AvinashRaj looks fine, what's wrong with it?

Avinash Raj

command executes successfully but awk: 1: unexpected character '.' error warning shown

please try that for me.

@AskUbuntu may i ask question as "I wanna a script to do this function.Plz someone recommend me"?

I will provide self answer for this question.

terdon

@AvinashRaj NO! You can post your script and ask for help fixing it but do NOT ask people to write a script for you.

I still don't understand what the error is, are you using Ubuntu?

Avinash Raj

2:30 PM

yes, i'm running Ubuntu 13.10

@terdon script completed and it works :-)

it doesn't had any errors.

terdon

OK, that makes more sense, there is nothing wrong with the command you were running.

Avinash Raj

then i will go for ( /W:/ && /launchpad/ ) search pattern only

is that possible to give 3 search patterns

W: , launchpad , net

terdon

yes. I'm sure you can figure out how

Q: should people who answer a question actively prevent duplicates?

If I see a question I can answer, I answer. If I know it has been answered recently. I point to the existing post in a comment. However if you have to search actively before giving (every) answer if it is a possible duplicate, it will slow down the process. What is the general idea? (Although I ...
