Linux, an open-source operating system, is renowned for its powerful command-line interface, providing users with extensive capabilities to interact with the system via the terminal. Among the most common commands used for navigating the file system and working with files are cd, pwd, and ls.

These are the most common commands that you will encounter frequently throughout the course.

The cd command is used to change the current working directory in the system. For instance, if you want to navigate to the "Documents" directory, you can execute the following command:

Executing this command without arguments will redirect the user to their home directory.

The pwd command (an abbreviation for "print working directory") prints the full path of the current working directory. It allows the user to quickly determine their current location in the file system. For example:

The ls command is used to list files and directories in the current working directory.

These commands are fundamental for working in the Linux command-line environment, providing users with a convenient and powerful way to manage the file system. Mastering them makes you a more efficient Linux user.

Why do we need this?

Moving from one directory to another opens up broad possibilities for managing the file system. It allows us to quickly locate and work with necessary files and directories, including organizing files into logical groups or accessing different parts of the system. Additionally, it facilitates the automation of operations such as file processing and copying through scripts, making the workflow more efficient and productive.
