Basics of Linux Operating System and Command Line

Mastering the command line

The command line is a tool for interacting with a computer using only text (also known as a text interface) rather than other methods like clicking and scrolling.

UNIX command is a type of command that’s used in Linux and macOS.

$ → is a symbol often used to signify where you can begin typing in commands.

We’ve learned how to use the cd command, but we don’t know how to move to the parent directory yet. If you want to move to the parent directory, you can use a special symbol .. , like cd .. .

If you execute cd without specifying a directory, you can move to what is known as a home directory. The home directory is represented by ~ as shown in the image below.

The Home directory refers to the base directory for the user. Since it’s important, moving to the home directory is made to be easy. /home/progate is the home directory for this lesson.

From this point on, we’re going to learn how to perform a variety of operations like moving, copying, and deleting files with commands.
