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.

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:

cd Documents

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:

/home/user/Documents

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

Desktop  Documents  Downloads  Music  Pictures  file.txt

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 possibilities for managing the file system. It helps to quickly locate and work with files, organize them into logical groups, and access different parts of the system. It also supports automation of tasks like file processing and copying through scripts, improving overall workflow efficiency.
