What does the command 'pwd' do in a Linux terminal?

The command 'pwd' stands for "print working directory." When executed in a Linux terminal, it outputs the full path of the current directory you are in. This is valuable for users who need to confirm their current location within the file system, especially when navigating through multiple directories or executing commands that require specifying paths.

For example, if a user is working within a hierarchy of directories and wants to ensure they are in the correct one before proceeding with a file operation, running 'pwd' provides an immediate reference point. This functionality is fundamental in a command-line environment where visual cues such as graphical interfaces are absent.

Other options do not pertain to the function of the 'pwd' command and perform different tasks such as changing the directory or listing files, which pwd does not do.
