1.14.1 - Brief Overview
Besides the desktop graphical user interface (GUI), there is also a command-line interface (CLI) that is more commonly known as the terminal. The terminal can be launched by selecting Start > Accessories > Terminal or using the keyboard shortcut Ctrl + Alt + T.
A command is typed using the keyboard and pressing the Enter key. For example, typing the command ls and pressing Enter will list contents of a directory and ls -l will list contents of a directory with more detail.
