Linux by user`s eyes: Software Distribution

Windows-style can form some bad habits, it will impede to You to use Linux. Don't find a sofware in the Internet!

A distributive of the Linux is the Kernel and some huge software set. Little part of this set would be installet during installation of the Linux, other part (it contains 10 000-s items!) is optional. This optional part is contained in repositories. You can install any program from a repository by 1-2 easy steps by a Package Manager (PM).

How to install the Firefox on Ubuntu, for example:

# apt-get install firefox

If You are afraid of the CLI, then You may use some GUI for PM, like the Synaptic

Linux by user`s eyes: Installation

An installation of user-friendly Linux distributive is more simple than Windows installation!

1. Simple installation for blonde girls

Go to the official site
Download a .iso file of the Linux
Burn the .iso on a CD
Load the CD into a comp and reboot
Press buttons "Yes" until the installation will be completed
Be happy!

2. Expert insallation with saving your Windows

Check any items where is written something about Windows and be happy. Linux never kills Windows without asking! You will have a ability to choose between Linux and Windows after the installation.

Moreover, Linux can resurrect old dead Windows on missing partitions!

Linux by user`s eyes: Command Line

Most of Windows-users are very afraid of the Linux Command Line, like this baby.

Don`t worry, You can ignore the CLI with user-friendly Linux, like Ubuntu.

But now we will try to learn the CLI a little.

Start the gnome-terminal for working with CLI on our computers in this class.

Learn at first those commands: ls, cd, touch, cp, mv, cat, rm, which provide basic file manipulations. Start a editor Geany by geany &. Start a browser by google-chrome &. Use those keys:

Up arrow calls previous command;
Tab completes commands and file names;
Ctrl + L cleans the terminal;
Ctrl + C stops the command.

After some such exercicies You will be able to crack the Pentagon! :)

DESKTOP ENVIRONMENTS

DE is a set of many programs for work:

The Desktop with non-boring wallpapers and system panel with some applets like the "Start" button or a clock;
User applications: a browser, a office suite, a mail client, a picture viewer, a video/audio players, a games;
System tools: a settings manager, some monitors, a software center, a sessions manager.

DE in Linux:

Here are many different DE-s;
You can install many DE-s on your system and choose bitween them;
You can stop a DE, restart a DE, remove a DE from your system and install new DE during one Linux session!

Differences bitween DE-s:

There are Qt-based and GTK-based DE-s, they are not compatible!
Some DE-s are huge and monstrouse, some DE-s are too minimalistic, there are stupid or very exotic DE-s... Choose your DE!
Any DE can be upgraded and customized. Starting set of software and DE's appearance is not fatal necessary!

Complicated. Customizable. Powerfull
