Using the terminal, you can navigate the file system with basic commands:

• pwd: Displays the current working directory.

• ls: Lists the contents of a directory.

• cd [directory]: Changes the current directory.

• mkdir [directory_name]: Creates a new directory.

File Permissions

Linux file permissions control who can read, write, or execute a file or directory:

• User (u): The owner of the file.

• Group (g): A group of users with shared access.

• Others (o): Everyone else.

Permissions are displayed using symbols (e.g., -rw-r--r--) where:

• r = Read

• w = Write

• x = Execute

Summary

The Linux file structure is a powerful and organized system that allows for flexibility and robust management of files and directories. By understanding the purpose of each directory and using basic navigation commands, you’ll have a strong foundation for working in Linux. In the next lesson, we will delve into essential Linux commands to interact with the system effectively.
