Command Line
The command line is a text-based interface for interacting with an operating system or software, where users type commands to execute tasks such as file management, system administration, and running programs. It provides direct access to system functions and is often more efficient for automation and scripting compared to graphical user interfaces (GUIs). Common implementations include shells like Bash, Zsh, and PowerShell, which interpret and execute the commands.
Developers should learn the command line because it is essential for tasks like server management, version control (e.g., Git), and automation through scripting, enabling faster and more precise control over systems. It is particularly useful in DevOps, system administration, and development workflows where GUI tools are limited or inefficient, such as in remote servers or continuous integration pipelines.
