What is the command line interface?
The command line interface is a text-based interface that allows you to interact with your computer using commands typed on a terminal window. It provides access to the underlying operating system, and with the right commands, you can perform a wide range of tasks, such as creating and deleting files, managing processes, and configuring system settings. The command line interface can also be used to run scripts or automate tasks, making it a powerful tool for advanced users or developers.
