Linux Terminal

What I like when I work with linux is the console. Instead using mouse to run Evolution to check my email, I just use:

Alt-F2

type “evolution

then press “enter” button.

 

You can do to another program, such as:

type “xmms” for music

type “xterm2” for terminal

type “konsole” for terminal (Not automatically installed in Ubuntu Feisty, you have to download it with command: $sudo apt-get install konsole).

type “konqueror” for File Manager (Not automatically installed also in Ubuntu Feisty, you have to download it).

etc….etc….

to close, just type “exit” and press “enter” in the terminal.

Ubuntu Repository

When the first time I used Ubuntu, I always thought why Ubuntu has Repository.

Then finally, I realized what a good thinking to provide a function like this in an Operating System.

I think, the most advantages are

  • save your time when you re-install your OS.

  • you can make an update all your clients in a LAN by pointing their’s repository to a server.

 

In Ubuntu, the repository file is located at:

/etc/apt/sources.list

You can modify it with gedit or vim, such as:

$sudo gedit /etc/apt/sources.list

 

Before you make any changes a configuration file in Linux, always make as a habit to back up the configuration. Just do as below:

$cd /etc/apt

$sudo mv sources.list sources.list.bak

 

or you can do like this:

$sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak

 

Usually, I disable the repository source that I don’t need for the moment with character ‘#’. It’s very easy, just put the ‘#’ in front of ‘deb’. I suggest do not delete it because may be you need next time.

 

For Samples:

# ================================================================

# Repository from Main Server

deb http://archive.ubuntu.com/ubuntu/ feisty main universe restricted multiverse

 

# ================================================================

# Repository for Compiz Fussion

# deb http://download.tuxfamily.org/3v1deb feisty eyecandy

# deb-src http://download.tuxfamily.org/3v1deb feisty eyecandy

# ================================================================

# CANONICAL COMMERCIAL REPOSITORY (Hosted on Canonical servers, not Ubuntu

# servers. RealPlayer10, Opera, DesktopSecure and more to come.)

# deb http://archive.canonical.com/ubuntu feisty-commercial main

# ================================================================

# E17 repository “edevelop.org”

# deb http://edevelop.org/pkg-e/ubuntu edgy e17

# deb-src http://edevelop.org/pkg-e/ubuntu edgy e17

 

This is what I’m talking about. You can update your Ubuntu via local network. It mean, you

can do it also with 2 computers. Just point to folder and IP address of the repository source.

# ================================================================

# Repository via local Network

# deb http://192.168.0.6/ubuntu7.04/ feisty main restricted universe multiverse

 

If your friend create a local repository in his laptop and you want to update via Ethernet cable,

you can do like this:

deb http://your_friend_ipaddress/your_friend_repository_folder/

for example:

deb http://192.168.1.5/repo_ubuntu/
