To give you an idea of the simplicity of a CLI, here is a command to let you know your computer's complete network information. By memorizing only a few keywords and simple syntax, you'll have powerful time-saving commands to save you from all the frustrations of a poorly designed GUI.
But there isn't much reason not to learn a few CLI commands. However, the few times you would need to use a CLI are when it really matters.įor the majority of people sticking to a GUI-only experience should be enough. Indeed, you won't miss a lot from using only a GUI. With the intuitiveness and the non-existent learning curve to using a GUI, most people won't have a problem interacting with their computers. With intuitive illustrations and interactive elements clickable through a mouse, GUIs have allowed all kinds of electronic devices to be used by just about anyone. GUIs have helped make computers as user-friendly as possible. It is a way to control a device through interactive graphical icons, menus, widgets, images, and just about anything you are seeing on your screen right now. In contrast, a GUI is one that everyone is probably using on a day-to-day basis to control their devices.Ī GUI is everything graphical illustrated on your display. As you learned earlier, a CLI commands a device through written commands inside a terminal. Now that you know what a CLI is, let's compare it to GUIs and see if people would ever need to use a command-line interface.Ī command-line interface (CLI) and a graphical user interface (GUI) are two ways people interact with a computer. Depending on your usage, controlling a computer using CLI can be as simple as a one-word command or complex composed of multiple lines of CLI commands known as a script. The shell languages used in a CLI are easier to learn than regular programming languages like C, Java, and Python.

Windows uses what is known as PowerShell, while Linux and macOS use Bash (Bourne Again Shell) and Zsh, respectively. The programming language used in a CLI is known as a shell language.
The format of these keywords (commands) is called syntax. Today, despite the invention of the mouse and graphical user interface, a CLI is still an important tool used by programmers, network administrators, penetration testers, and power users.Ī command-line interface or CLI controls a computer by giving it a line of structured keywords. This terminal used to control a computer is known as a command-line interface or CLI. This language is then used on a terminal to do everything, from simple tasks to complex automation. For this reason, programmers designed a robust and straightforward shell language that everyone could use to communicate with a computer.
In the earlier days of general-purpose computers, a keyboard was the only thing you could use to control a computer.
