Use the command line with Konsole

Konsole is one of the most important and helpful programs on Kubuntu. Important because you can do just about anything with it.

To be precise, Konsole is a terminal emulator running BASH (Bourne Again SHELL). A terminal is what you get when you strip away all the extraneous parts of a computer like the graphical user interface, etc… and end up with a black screen and a cursor. A shell is basically the system you use to put commands into the terminal.

For instance, if you type the command,

echo $SHELL

or copy and paste it for that matter the terminal will output,

/bin/bash

which is the path to the bash program.

There are a number of commands that are used commonly in Konsole but the most commonly used ones are,

apt  - For installing and removing programs.
clear- Clear terminal.
exit - Exit terminal.
ls   - List the contents of the directory.
cd   - Change directory (cd .. to go up a level).
sudo - run commands as admin or super user.
top  - See what processes are running (push q to end).

Installation

Konsole is preinstalled on Kubuntu and can be found in the Applications Menu under Applications/System/.
