The Terminal is a powerful command-line interface that allows you to interact with your Mac's operating system using text-based commands.

  4. Double-click on the "Terminal" app to launch it.

Once you're in the Terminal, you'll be ready to unleash the power of the command line.

With these commands, you'll be able to navigate, create, and manage files and directories right from the Terminal.

The Terminal also allows you to manage processes running on your Mac. Here are a few commands to help you with that:

  • top: Display real-time information about system processes.
