Kontrollilinja

Kontrollilinja is a Finnish term that translates to "control line" or "command line." In computing, it refers to a text-based interface for interacting with a computer's operating system or software. Users type commands and receive responses in the form of text. This contrasts with graphical user interfaces (GUIs), which use visual elements like icons and windows.

The command line interface (CLI) has been a fundamental part of computing since its early days. It allows for precise control and automation of tasks. Many system administration tasks, scripting, and software development workflows still heavily rely on command-line tools due to their efficiency and power. Common examples of command-line interpreters include Bash, Zsh, and PowerShell.

While GUIs are generally considered more user-friendly for everyday tasks, the command line offers advantages in terms of speed, scriptability, and access to advanced functionalities. Many developers and system administrators prefer the command line for its flexibility and the ability to perform complex operations with a single command or a series of chained commands. Learning to use the command line can significantly enhance a user's proficiency with computers.
