What is the Mac Terminal? A Beginner's Guide to the Command Line Interface on macOS

The Mac is great for productivity and professional use. This is also one of the main reasons why it's not so great for gaming, but we'll park that discussion for now. Because the Mac is built for productivity, it equips users with powerful tools to tackle productivity challenges.

One such tool is the Mac Terminal CLI, which gives users the ability to control their entire Mac system. But what exactly does it do? And should you be using it? If so, how do you use/open it in the first place?

In this article, we will answer these questions and more. So, let's get right to it.

What is Terminal on a Mac?

The Mac Terminal is a command-line interface (CLI) that provides access to UNIX command-line utilities. It's a powerful tool for developers and system administrators, offering features like scripting and file management.

The Mac Terminal app can be used to create scripts that run commands in sequence from top to bottom. It can also be used to chain commands together so they execute one after the other automatically, without requiring the user to input anything between them.

The Mac Terminal has many other features, such as file management, text editing, viewing text files, and navigating directories. However, usage of MacOS is largely limited to power users, as it is based on BSD Unix, which can be somewhat arcane for the average user.

What is Terminal on a Mac used for?

When it comes to the Mac's Terminal, the fundamental thing to understand is that it's simply an application. If you're familiar with Windows, you might know it as the Command Prompt. However, the latest versions of Windows 11 also refer to it as the Terminal.

A Terminal, also known as a command-line interface (CLI), is designed to provide users with a means to interact with their computer system through text-based commands. When users input various commands, the terminal executes those commands, performing tasks such as formatting disks or searching for specific files, among many other important functions.

To find it, press Escape and then Y to open the command palette, where you'll find many of the things you can do in a terminal.

• Managing the deeper aspects of a device
• More efficient formatting or handling of partitions
• Removal or troubleshooting errors from the command line
• Automating critical tasks with shell scripts
• Having comprehensive control over hardware
• Consuming fewer resources when performing resource-intensive tasks

This means that a terminal usually takes up only a few MB of your RAM. So, it does the same job as a GUI (graphical user interface) with less memory. It also performs tasks more efficiently, for example, when formatting a partition.
