Summary: This post is a beginner's guide to Terminal, the Command Prompt on Mac. Everything you need to know is covered, including how to open and use Terminal on Mac and a list of some commonly-used commands.

A beginner

We are all familiar with the graphical user interface that we use daily to interact with our Macs, but not so much with the Mac command-line interface - Terminal. It's the macOS version of Windows's Command Prompt and is very helpful for people who are used to command lines.

It has the advantages of being more efficient with tasks, troubleshooting issues, and repairing disks through SSH or Mac Single User Mode when you lose access to the user account.

Let's start with some basics to help you dig deeper and work with complicated tasks in the future.

What is Terminal on Mac?

Generally speaking, people use two interfaces to communicate with computers: GUI (graphic user interface) and CLI (command-line interface). 

The Terminal app provides a command-line interface on Mac computers to allow you to control the operating system quickly and efficiently to perform tasks a graphical user interface is unable or requires more effort to deliver.

How to open Terminal on Mac?

If your Mac works well, you can launch Terminal from Desktop through Spotlight or Finder. Otherwise, you can access it from the macOS Recovery mode. If unfortunately, the Terminal is not working, follow: Mac Terminal is not working, what to do?

How to open Terminal from Desktop?

The easiest way to open Terminal is from Spotlight search. Click on the small magnifying glass icon at the top-right corner of your Mac or press the Command + Space keys at the same time to launch Spotlight. Then you can type in "Terminal" and double-click the appeared Terminal. app to open it.

You can also find it in the Utilities folder under Applications in Finder.

If you plan to use Terminal often, you can pin it on the Dock by right-clicking on the Terminal icon and choosing "Keep in Dock" from the Options menu. If you prefer to open Terminal on Mac with a keyboard only, you need to create a shortcut.

How to open Terminal from macOS Recovery mode?

To launch Terminal on an Intel-based Mac, you need to boot your Mac into macOS Recovery mode by holding down Command + R keys until you see the startup screen at restarting.

For M1 Macs, you need to shut down the computer first and press the power button until you see "Loading startup options", then click Option > Continue. Upon the macOS recovery window, you can pull down the Utilities menu and click on Terminal to open the Terminal app.

How to use Terminal on Mac?

Once you open Terminal, you will see a small window with the title listing the name of the current directory, the type of the shell, and the window's size in pixels. A command consists of three parts: the command name, a modifier to the command's output, and where the command will operate.

Terminal window elements explained

  • Commands won't execute until you press the return key. If you mistake the code, you may receive an error message, or the command will run in the wrong way.
  • You can use the up arrow key to repeat a command. If you want to clear a window occupied with texts, simply type in clear and press Return.
  • You usually need to go to Finder to see the changes you made with Terminal, except the command requires a new window display.

Basic Mac Terminal Commands

We will explain some common commands you can use to finish simple tasks in this section. If your file system is case-sensitive, Terminal can only recognize the original name, so Desktop can't be desktop. When you are unsure which directory you are in, enter pwd to make a check.

How to kill a process in Terminal?

Forcing a process to quit will cause you all the unsaved changes, so ensure that the target process is the correct one and save the changes you made. There are two ways to kill a process with Mac Terminal.

To terminate a process immediatelykill PID number

If you want to force quit Music, type top in the Terminal window and press Enter. Then find the PID number of Music and type q to return. You can now enter kill 1234 to exit Music immediately (suppose the PID number of Music is 1234).

To kill all the processes via the killall command with the specific namekillall process name

If you need to terminate all processes with Google, input killall Google.

 Warning: Mac Terminal won't ask you to confirm if you really want to kill a process, so use these commands sparingly.

If you simply want to interrupt a running process in Mac Terminal, you can press Control-C.

How to change directory in Terminal?

To change directory
cd ~/desired directoryor
cd desired directory

By default, you are brought to the home directory when you open a Terminal window. If you need to navigate to another folder, you can use the cd command in the Mac Terminal along with the "desired directory" you want to open. E.g. switching to Desktop, insert cd desktop. Don't forget to press Return after inputting the command.

How to list a directory in Terminal?

After using the cd command to switch to the desired directory, you can utilize ls to view all the files or folders inside it.

How to create, open and delete a directory in Terminal?

Create a new folder:mkdir folder name

Create a new file:touch filename.format

For instance, I want to create a folder named test1. I will then put in mkdir test1 and press Enter. Now inside this folder, I can enter touch sample.txt to generate a txt file called sample.

Open a file under the current folder:open filename

Open a file in another folder:open file path

Open an application:Open -a Application name

Open a file with a specified appOpen -a app name file path

For example, to open the Music app, you can enter Open -a music. If you need to open a file with a specified app, let's say open a file called sample.txt with WPS Office, you can use Open -a wpsoffice /Users/jenny/test1/sample.txt. The file path can be easily dragged and dropped to the Terminal window.

Delete a file:rm filename

Delete a folder:rm -r folder name

Files deleted by this Mac delete command line are gone forever, and there is no way to get them back. So be cautious!

Copy files from one folder to anotherditto folder 1 folder 2

Folder 1 contains files you want to copy, and folder 2 is where you want to paste the files.
