I would try finding the version of setuptools that matches your python version

How do I pipe a command output into a new text file?

I am using Skype version 4.3.0.37-1 on Ubuntu 14.10, and I am not able to hear anyone, and neither are they able to hear me through Skype. I had a look at the answer to this question, but it did not help, and I still have not been able to find a fix for this: Can't hear people on skype I also do...

Q: What are the shell's control and redirection operators?

@ByteCommander See here for the full list:

7

I often see tutorials online that connect various commands with different symbols. For example: command1 | command2 command1 & command2 command1 || command2 command1 && command2 Others seem to be connecting commands to files: command1 > file1 command1 >> file1 What are these things?...

bash shell

Thanks, it's done.

@Toroidal You probably need to choose the right device in skype's sound settings.

What is this?

bytecommander@AlkaliMetal:~$ /home/bytecommander/ez_setup.py
bash: /home/bytecommander/ez_setup.py: Permission denied
bytecommander@AlkaliMetal:~$ sudo /home/bytecommander/ez_setup.py
sudo: /home/bytecommander/ez_setup.py: command not found

Why does sudo not find the file???

5:11 PM

you are not in the sudoers.file

I CAN sudo!

@terdon I made mention of the same thing

@ByteCommander The permission denied is 'cause the file's not executable.

The second is weird though.

sudo command not found should be root issue

It just does not find the file in sudo, but I can list it with sudo ls /home/bytecommander/

sudo is working except on this file!

5:13 PM

@Virusboy No, sudo was found. It's sudo that's complaining about the py script not being found.

I chmod +x now.

@ByteCommander That should fix both issues.

Hi all

hi

bytecommander@AlkaliMetal:~$ sudo /home/bytecommander/ez_setup.py
sudo: unable to execute /home/bytecommander/ez_setup.py: No such file or directory

5:14 PM

I'm guessing that since sudo found no executable file there, it looked for something called /home/bytecommander/ez_setup.py in $PATH, failed to find it and gave that error./

i have KAOS as my kde os

@ByteCommander sudo python /home/bytecommander/ez_setup.py

bytecommander@AlkaliMetal:~$ /home/bytecommander/ez_setup.py
bash: /home/bytecommander/ez_setup.py: python: bad interpreter: No such file or directory

want to have the cat of the file?

@ByteCommander Yeah. The shebang line is wrong. That's why sudo couldn't find it either.

run it in GUI

5:15 PM

@ByteCommander Just run it with python as I said. Or show the output of head /home/bytecommander/ez_setup.py

bytecommander@AlkaliMetal:~$ cat /home/bytecommander/ez_setup.py
#!python
"""Bootstrap setuptools installation

If you want to use setuptools in your package's setup.py, just include this
file in the same directory with it, and add this to the top of your setup.py::

from ez_setup import use_setuptools
use_setuptools()

If you want to require a specific version of setuptools, set a download
mirror, or use an alternate download directory, you can do so by supplying
the appropriate options to ``use_setuptools()``.

user136984

hmmm

that drop down bugs me

Ah, yes. "python /home/bytecommander/ez_setup.py" works

are you running any vms?

5:16 PM

@ByteCommander Yeah, wrong shebang. That should be #!/usr/bin/python or, better #!/usr/bin/env python

@Toroidal Yes, you'll want to change from virtual device to whatever your actual sound card/mike is.

KasiyA

Do you know why awk sorts the arrays inside itself? for example I want to extract lines 2,8,5,6,3 from a file and print them in previous order but awk gives me the sorted lines. prints lines 2,3,5,6,8 instead of 2,8,5,6,3 that I want. Is there any option for awk to disabling its Sort? thanks

user136984

@terdon That's part of the problem, I am unable to change to anything else, I clicked the pull-down menu, and "Virtual Device" is all that is there.

bytecommander@AlkaliMetal:~$ sudo python /home/bytecommander/ez_setup.py -U setuptools

@Toroidal Ah, add that to your question. That's where the problem is.

But still the same error for pip:

5:18 PM

but sound is coming out of other apps?

@ByteCommander yes, that was the same version as you tried before.

Seriously though, I don't know crap about python. I;m just shooting in the dark here.

user136984

@terdon Ok, I've added that information to my question. :)

user136984

@Virusboy Yes

@ByteCommander you need to check if the file can be run in GUI and what the error from that is

@Virusboy What GUI?

How can a GUI be more informative than the CLI anyway?

user136984

5:20 PM

@Virusboy Yes

Ubuntu-desktop

I ask Terdon for reason about python

@Virusboy Huh?

@Toroidal i dont know, never seen that happen is it a bug

nvm @terdon

What what what? What do I have to do now? I added the new error and what I did to my question.

Link again: askubuntu.com/questions/598792/…

ooooo that makes sense

5:24 PM

And I just wanted to listen to the radio -_-"...

do you have multiple ones installed?

multiple what? explain as if I was five, please... Never had to do with python before.

(And now I know why snakes are called evil.)

is 2.7.8 python the one and only one installed on your Ubuntu?

I don't know. How do I check? It's the only one I found and python --version puts this out.

hrmm i dont remember

i usually check the software center

@Virusboy Got something!

@ByteCommander Pro tip: ls /usr/bin/python*

Seems like python 3.4 is also installed.

@ByteCommander Try running python3 /usr/share/streamtuner2/st2.py

IT RUNS! ^_^ =D

It prints a lot of crap and warnings into the terminal, but it runs!

1 hour ago, by terdon

@ByteCommander In that case, I'm guessing you're either 1) installing in a place your python is not checking or 2) installing them for a different python version. I understand that python2 and 3 are both available and use different packages.

I guess it was option 2 then :)

OK, simplest fix is to edit the 1st line of the script and change it to #!/usr/bin/env python3

5:34 PM

okay...

That way,, the script will use python3 by default.

Thank you finally. I think that is working now.

I hope I did not mess up the whole stuff too much by trying to repair it.

What shall I do with my question now?

@ByteCommander I doubt it. You seem to have gotten it back to normal. Also, I'd delete that question since the actual issue was completely different and it will be hard to debug.

nuked.

But I just have another problem...

Are you still fit?

No snakes this time ;)

Heh, try me.

I'm always fit!

5:40 PM

What logs or whatever do I have to check to debug logout hangs? My brother logged out an hour ago and it got stuck with his blank wallpaper.

(That was not the word you wanted :)

@ByteCommander ~/.xsession-errors probably

Q: How to prevent awk from sorting the array?

I went to TTY1 (black screen without any words/underscore) and back to TTY7, which showed me a redirection message and pushed me to the login screen.

That worked, because my admin user was till logged in.

When I logged out of my admin user yesterday, it was the same, except that TTY changing to 1 and back to 7 left me at a black screen (did not reload the wallpaper or redirect to anywhere) with a mouse screen. Tapping the power button then shut it down

I'm trying to extract those lines from data text-file: first second third fourth fifth sixth based on their lines numbers pre-saved in nums text-file: 2 6 3 and I ended up by the following awk solution but it gives me the lines which are sorted based on their line-numbers and not according ...

Maybe the last entry in the log of my brother's account?

@terdon Still alive? Or did I shock you with my messed up machine?

@ByteCommander What does beendet mean?

And who uses xfce? You or your brother? The other messages were unity. DO both have the same issue?

beendet = exited

Sorry, there is no auto-translate for logs...

Both accounts were running an xubuntu session.

But it is the unity-greeter.

Might that be incompatible?

No idea. I haven't touched unity.

6:00 PM

Hmmm... :-/ Ask a question?

@ByteCommander Probably :)

Does the list of still active processes of my brother's half-logged-out account help?

Try deleting .xsession-errors, then logging out again so you can see what errors were reported

How do I get a list of processes for an user?

@ByteCommander I doubt it. Could be anything

@ByteCommander ps aux | awk '$1=="terdon"'

6:02 PM

Maybe it helps to see which processes were not terminated yet?

Try it

I'm pretty sure he has logged out and the problem is that the greeter is not coming back though.

More than I expected. See:

bytecommander@AlkaliMetal:~$ ps aux | awk '$1=="patrick"'
patrick  21693  0.0  0.0  74372   996 ?        Sl   16:07   0:00 /usr/bin/gnome-keyring-daemon --daemonize --login
patrick  21695  0.0  0.1   7804  2088 ?        Ss   16:07   0:00 upstart --user
patrick  21834  0.0  0.0   5696  1792 ?        Ss   16:07   0:00 dbus-daemon --fork --session --address=unix:abstract=/tmp/dbus-f4CtVhgIj8

But when I tried to shut down as only user logged in, it also got stuck.

Then the greeter should not have come up at all, right?

So that's probably not the cause.

user136984

Now that is odd...

user136984

If I say something in () and then remove it, and then type it again, it just disappears...

user136984

Even if I just do "()"! :D

user136984

How strange...

still there.

remove manually...

(test)

still there.

user136984

You have to do straight after.

user136984

So do one, then remove, and then do another one.

(i want to be removed too)

erm... No?

user136984

It has to be the same message.

user136984

6:08 PM

:D

(hellooo)

user136984

I don't think that that was the exact same message...

yep, true. It just pops away until you spell it different!

user136984

:D

user136984

Why though?

6:09 PM

Strange.

But does not solve my logout problem!

And only in parentheses?

No, parentheses aren't needed.

They must be deleting by matching the user to the text so the next one is also picked up.

@ByteCommander And does it happen with any DM or only xfce?

Probably they think if you e.g. accidentally posted your credit card pin and quickly delete it, they can prevent you from accidentally post it again...

@terdon It occurred only the last two times with xfce. Unity never until it started, but xfce also was working until yesterday evening.

I don't know if it's broken for Unity too now.

Phew, that was close :)

terdon what are you doing?

@ByteCommander Does it survive a restart?

@Virusboy Posting my pin number. Obviously :)

Nothing more secure than 1234.

Q: Next message (if same as previous removed message) just disappears too

6:15 PM

@terdon @ByteCommander: Ok, I have posted a question about the weird message disappearing act here:

user136984

When in chat I type something and then I delete it. If I then type the exact same thing and send it right after I sent the one that I deleted, it disappears. Why is this so? Is this a bug? Or by design?

user136984

:D

@terdon My machine NEVER survives a restart, because my graphic card will present ma a blank white screen when it is (re)started hot.

@ByteCommander Oh, yeah. Forgot that.

You really should look into getting a new machine. You can get perfectly decent desktops pretty cheap these days.

/cc @Lucio ^

@Toroidal I think it only asks if the package you're installing depends on other packages as well. Since that will cause packages you did not actually chose to be installed, it asks you.

A better question is why in the world you would want to be asked for confirmation every time?

user136984

@terdon Because sometimes I may miss-type the package name, or just somehow accidentally get the wrong package. So a confirmation would be nice. I might also notice that the package is much larger than I expected, which could mean that I may not want to install it, or that I will need to make changes to my systems before doing so. It would just be nice to be asked to confirm before it finally installs.

@Toroidal I answered.

@Toroidal Ugh. I hate confirmation. That's so Windows: "Users are stupid, let's protect them from themselves".

@Toroidal Related to your issue, is it true that sometimes even I'm asked [Y/n] if i press Enter, the installation is aborted.

user136984

7:09 PM

@IonicăBizău Well, if anything else is typed instead of 'Y', even if that is nothing, then it should abort.

@Toroidal I will edit my answer after diner. I found something interesting!

user136984

@ByteCommander Ok, what's for dinner? ;D Broccoli?

@Toroidal No, just enter. It happened to me many times. Actually when doing upgrade.

user136984

@IonicăBizău No, that's what I meant, if you type nothing and then just press enter, it should abort. Probably a bug if it does not.

@Toroidal Do you want it to just show you the command you ran and ask whether you want to run it, or do you want all the info from apt?

7:12 PM

@Toroidal [Y/n] isn't supposed that Enter means Yes (default)?

user136984

@terdon All the info from apt would be preferable.

user136984

@IonicăBizău Enter should abort, and always does with me... I think... Oh dear! Now I'm starting to doubt myself! :D

@Toroidal Hmm... Isn't that a standard? Enter will run the default one (the one with uppercase): Y/n + Enter == Continue, y/N + Enter == Stop, y/N + Y == Continue and Y/n + N == Stop. That's everywhere... Isn't it?

user136984

@IonicăBizău Well, even if pressing enter without entering 'y', is meant to pass a confirmation, it just doesn't feel right... There should be only one confirmation option, and it shouldn't be as easy to type as just enter.

I'm getting some strange errors from dmesg on a new Ubuntu Server installation:

I get the cold

Aren't Chinese chicken the promotor of the Influenza virus?

Influenza is just the flu.

oh yeah - I remember faintly... it was the birds that had to be killed everywhere.

I want to write a short text before each file size to describe it.

I don't know sed yet... Haven't read that far in the Linux admin manual yet...

(sed command is written above ^)

what's the output?

Example:

The two sizes. I want to change it to something like:
