Did you know that there are over 100 million Mac computers in use as of 2022? A large segment of Mac users also uses them for software development, coding, and programming.
Developing computer apps with macOS can be a streamlined process, but only if you understand how to use the Mac Terminal app. We’ve put together a brief guide about the Mac Terminal for those who don’t quite understand everything that they should. Let’s get started.So.
What Is Mac Terminal?
Mac Terminal is a command-line interface (CLI) for macOS. It provides a text-based way to interact with the operating system, allowing users to enter commands and receive responses.
The app first appeared in NeXTSTEP, the predecessor to macOS, and has been included in every release since then. While some users may never need to open Terminal, those who are interested in coding or developing apps will find it to be an essential tool.
Terminal provides access to a wide range of features and functions that are simply not available through the graphical user interface (GUI). In addition, many popular coding languages can be run directly through Terminal. Let’s explore how you can get started using it.
Opening the Terminal
The first step is simple: open the Terminal app. This can be done by searching for “Terminal” in Spotlight, or by opening the “Utilities” folder in your Applications folder.
Once the app is open, you should see a mostly-blank window that says the name of your Mac user and the device you’re working with. You may notice that the default Terminal window is quite small. You can resize it by clicking and dragging the bottom right corner of the window.
Now that we’ve covered some of the basics, let’s move on to using the Terminal for its intended purpose: entering commands.
Entering Commands
Commands are entered into Terminal by typing them out and pressing the “return” key on your keyboard.
Each command is made up of one or more arguments, which are small pieces of information that provide context for the main command. For example, the “ls” command is used to list all of the files and directories in the current working directory.
This command doesn’t require any arguments, so you can simply type “ls” and press “return.”
You’ll notice that the output of the “ls” command is a list of all of the files and directories in the current working directory, each on its own line.
The “pwd” command is used to print the current working directory. This is useful for determining your location within the file system.
The “cd” command is used to change the current working directory. For example, if you want to move from your home directory to the Desktop, you would use the following command: “cd Desktop”.
The “mkdir” command is used to create a new directory. If you want to create a directory called “Documents” on your Desktop, you would use the following command: “mkdir Documents”.
These are just a few of the most basic commands that you can use in the Terminal. As you become more comfortable with the app, you’ll find that there are many more commands available to you.
Can I Use Terminal to Build Entire Applications?
In short, yes. Terminal can be used to develop entire applications, though it is worth noting that this is generally not the recommended approach.
Most developers prefer to use a dedicated IDE (integrated development environment) for these purposes. For those who are unfamiliar with this term, an IDE is a program that provides a graphical interface and tools specifically designed for software development.
For basic tasks, though, Terminal can be extremely useful. For example, if you want to quickly view the contents of a file, you can use the “cat” command. This command will print the entire contents of a file to the Terminal window.
The “grep” command is another useful tool. This command can be used to search for specific patterns within files.
For example, if you want to find all instances of the word “apple” in a text file named “Reports”, you would use the following command: “grep apple Reports.txt”.
What Are Common Mistakes People Make When Using Terminal?
One of the most common mistakes people make when using Terminal is entering commands without understanding what they do. It’s important to remember that although Terminal is a powerful tool, and as such, it can be dangerous if used improperly.
Always take the time to research a command before you enter it. Another common mistake is failing to update software in a timely manner. Like any other software, the Terminal app receives regular updates that fix bugs and add new features.
It’s essential to keep your software up to date to ensure that you’re using the most recent version. Finally, some people make the mistake of assuming that they need to be experts in order to use Terminal.
While it is true that Terminal can be difficult to use at first, it is not necessary to be an expert in order to get the most out of the app. With a little practice, anyone can learn how to use Terminal effectively.

The Mac Terminal Application Has Countless Uses
Whether you want to write your own program or simply navigate through your computer’s files, the Mac terminal app is a powerful tool that you can take advantage of. Be sure that you keep the above information in mind so that you can get started using it correctly.
