macOS

The command line interface (CLI) is a text-based way to interact with your computer. Instead of using a mouse to click on icons and menus, you type commands and receive responses in plain text. Often referred to as the “shell,” the command line is a powerful tool that allows you to automate routine tasks and perform advanced operations—making it essential for developers and power users alike.

While macOS includes a robust command line environment similar to those found in Linux and other Unix-based systems, it does not come with a built-in package manager. A package manager is a tool that simplifies the process of installing, configuring, and updating software. It centralizes software management, allowing you to maintain all your tools and libraries efficiently in standardized formats.
