Ant's's questions

I'm very new to Ubuntu, all of a sudden my internet is not working in my Ubuntu machine.

But fortunately the internet is working in my Windows machine. The ethernet cable is not even gets detected in my Ubuntu machine.

As a new user to Ubuntu, this is really frustrating. Are there any ways to use internet in Ubuntu?

Edit:

Doing ifconfig eth0:

eth0      Link encap:Ethernet  HWaddr 6c:f0:49:c4:7f:2d  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1

Is there any way to find sleeping processes in Ubuntu?

I can see top can list out number of sleeping processes, but I want them to be listed with their name.

Are there any commands for that?

I have file like this :

 other lines . . .    
 blah blah blah (:34)

I wish to find the occurrence of numbers in the above file. I came up with:

grep [0-9] filename

But that is printing the whole:

blah blah blah (:34)

Rather I want only 34. Is there any way to do so?

I have installed play :

sudo apt-get install sox libsox-fmt-mp3

I can now play my audio files like this :

play Desktop/SONGS/01\ -\ Oh\ Baby\ Girl.mp3

Since I'm learning shell, I wish I could do something like this :

 (sleep 10 ; play Desktop/SONGS/01\ -\ Oh\ Baby\ Girl.mp3 ) &

After 10 sec's, I can see the screen as :

 File Size: 7.38M     Bit Rate: 260k
  Encoding: MPEG audio    Info: 2012
  Channels: 2 @ 16-bit   Track: 01/09
Samplerate: 44100Hz      Album: Maalai Pozhudhin Mayakathilaey :::tunesinn.blogspot.com:::
Replaygain: off         Artist: Hemachandra, Achu
  Duration: 00:03:46.98  Title: Oh Baby Girl

But the song is not playing. But if I do this (without &) :

(sleep 10 ; play Desktop/SONGS/01\ -\ Oh\ Baby\ Girl.mp3 ) 

Is working as expected. But I couldn't able to use my terminal in meanwhile.

How could I resolve my problem, with using &?

I read from a book where it says, the command rm deletes the inode and not the file. Which means if I delete with the rm command, then it cannot be restored.

I'm very new to Ubuntu environment. Now my doubt is, how does the Del key works? It is not deleting the inode as far as I am concerned, because I can restore it from my Trash folder. So am I right to say that Del key is doing a mv command to Trash folder leaving the inode unchanged? Or am I missing something here?

Symbolic links vs Hard links

I'm a new user to Ubuntu. And I do install some software. I see many tutorials uses symbolic link to a directory. Like this :

ln -s

Are there any advantages of using this way? Or it is the way it should be done?

I download JavaFx from here. I placed it in my home directory(anto) under the name javafx. Then I did something like this :

vi ~/.bashrc

and added the following lines:

javaFx_home=/anto/javafx/rt/lib/jfxrt.jar
export PATH=$PATH:$javaFx_home

But after providing the classpath, I tried running :

groovy MyProgram

(which depends on the JavaFx classpath).

But that throws me an error. Where I went wrong?

Well I have been using Ubuntu for past one year. Even though I'm not yet experienced with all the commands that Ubuntu provides, I like Ubuntu. In my college they use Windows. In such a situation how do I explain my teachers/HOD/Principal that Ubuntu is as powerful as Windows? I know I have said this:

1. Its a open source.

2. No virus.. All softwares can be installed easily

3. We can use Wine to run .exe applications.

Apart from these what all strong points can be given to change my college to Windows to Ubuntu?

I'm reading this tutorial. I need a turbo pascal, can anyone say me how to install turbo pascal in Ubuntu 10.04?

I have already installed Groovy in my Ubuntu 10.10 desktop version. Now Groovy 1.8. has been released.

When I try to install using the same command I used to install the previous Groovy version:

sudo apt-get install groovy

I get this:

0 upgraded, 0 newly installed, 0 to remove and 135 not upgraded.

So how can I install it?
