A Command Line Interface (CLI) is a interface for interacting with a computer or software application. Instead of using graphical elements like windows, icons, and buttons (as in a Graphical User Interface or GUI), users interact with a CLI by typing into a terminal or command prompt. CLIs are entirely text-based, which means users need to type commands and read text responses. This can be more for certain tasks, especially when automation or scripting is involved.
Users input commands in the form of text strings. These commands are typically composed of a command name followed by and options that modify the command's behavior. Each CLI has its own syntax and set of commands. Users need to learn the specific and their usage to be proficient in a particular CLI, making tasks like batch processing, system administration, and data manipulation possible through scripting.
Graphical User Interfaces (GUIs) are a type of user interface that relies on elements, such as windows, icons, buttons, and menus, to enable users to interact with computers and software applications. GUIs offer a more visually and user-friendly experience compared to text-based interfaces like Command Line Interfaces. They allow users to easily navigate and interact using pointing devices such as a mouse or touchpad, providing functionality that is generally more accessible for those accustomed to visual elements.
