Now that you have a computer, how you operate it?
Of course through various applications.
How do these apps operate the computer?
These apps actually operate the computer through commands.
Every macOS user has a Terminal app. It is the most powerful tool in our arsenal. You can operate all the commands through the Terminal app.
I recommend that you pin the terminal app to the dock, as you will be using it frequently in the future.
In the settings page, there are many themes available, and you can choose one that you like.
The macOS operating system supports multiple users.
Which user are you currently logged in as?
Type this command:
whoami
If you find font too small, press these two keys simultaneously: Command +
What is the current directory?
Type this command:
pwd
List all files and folders in the current directory:
ls### cd
Change the current directory:
cd ~/Download### rm
delete(remove) a file
rm temp.txt## Shell
The commands mentioned above belong the shell, which is a special user program that provides an interface for the user to use operating system services.
Are there any other commands?
Yes, of course.
When you need, just ask your AI Assistant!
Can we install other commands?
Yes!
And how?
We will learn that later.
Terminal is a powerful tool that serves as the interface for communication between user and the operating system The examples provided above are just the most common use cases. As you continue your learning journey, you will discover more advanced use cases.
