komentoriviliittymän

A komentoriviliittymä, often abbreviated as CLI (Command-Line Interface) in English, is a text-based interface used for interacting with computer programs or operating systems. Instead of graphical elements like windows, icons, and buttons, users input commands as text and receive text-based output. This contrasts with graphical user interfaces (GUIs), which are more common for everyday users.

CLIs are known for their efficiency and power, especially among developers, system administrators, and power users. They allow for precise control over system operations and can automate repetitive tasks through scripting. Many operating systems, such as Linux, macOS, and Windows, provide their own CLIs, like Bash, Zsh, and PowerShell, respectively.

Users type commands into a terminal or console window, specifying the program they want to run and any arguments or options to modify its behavior. For example, a user might type a command to list files in a directory or to copy a file from one location to another. The system then processes the command and displays the results in the same text-based interface.

While CLIs can have a steeper learning curve than GUIs, they offer significant advantages in terms of speed, resource usage, and flexibility for complex tasks. They remain an essential tool in many computing environments.
