Even if using graphical applications is very comfortable and easy for most people, the command line is a very powerful interface to interact with your system. The shell's main asset is the number of existing utilities: there are thousands of them, and each utility is devoted to a particular task. We look at a very small number of these utilities hoping that you will feel more comfortable interacting with your system through the command line.

 Choose System+Terminals → Konsole from the main menu to get a terminal window to have access to the command line. By default you will be “inside” your personal directory, named after your user name: /home/your_user_name.
