This document introduces the command line interface (CLI), noting that it provides an all-text display mode without a graphical user interface. It describes some advantages of the CLI, such as running commands that power graphical applications in the background, allowing multi-user logins and terminals, offering more flexibility and speed while using fewer resources than GUIs. The CLI also enables scripting and makes it easy to work on multiple files with single commands, especially for remote logins. The document lists some basic CLI commands and concludes with encouraging questions.
