What is Terminal?


Terminal or Konsole in Kubuntu is a place where you type a command and press Enter button to do a job. It's similar to Command Prompt on MS Windows. Here's how Konsole looks.

1. Getting Started


Learn more about 3 commands in the Basic APT Commands.

To begin with terminal in Kubuntu, try these 3 commands:

  • Reload (get list of software available from the internet):
$ sudo apt-get update

The result should looks like this:

Reloading, downloading index files


Then, you can find software you want by this command:

  • Search for software:
$ apt-cache search [software-name-here]
The example for GIMP should looks like this:

Searching

Then, you can install software you found by this:

  • Install software:
$ sudo apt-get install [software-name-here]

The example of installing GIMP should looks like this:

Installing

Tricks you could use for whole daily life:
  • Press Y for yes, and N for no while asked to install.
  • Press Ctrl+C to cancel a command.
  • Press Ctrl+L to clear screen.
  • Press TAB to autocomplete typing file name.
  • Uppercase and lowercase matter, so don't type incorrectly.

2. Navigate


To master terminal is the same as to master file manager. Do you use Explorer on Windows? What is the first thing you learn? That's simply the same: you first learn how to navigate between folders, that is, knowing your position and find your files. In the terminal language, that is using pwd, ls, and cd commands.

Try out these commands:
$ pwd
$ ls
$ cd ~
And it should looks like this:

Left=Konsole, Right=Dolphin, both showing the same folder ~/Pictures

3. Edit


You can edit files in Konsole, too. This is needed for changing sources.list, resolv.conf, or even squid.conf or any settings available in the Kubuntu system. How to do that?

The rule: press Ctrl+O to save file, press Ctrl+X to exit.

Editing system file:


Terminal in Dolphin!


Despite this has been already explained in the fourth part, it's very good to repeat that you can open Konsole inside Dolphin. This is much more easier for you so you don't need to type long folder address. This is most useful when you try to install .deb package (say, by you reading a tutorial from the internet) or fixing something on the system folders (e.g. installing WordPress).
