Which Linux command is used to display the current working directory?

The command used to display the current working directory in Linux is represented by "pwd," which stands for "print working directory." When executed, this command outputs the full path of the directory you are currently in, allowing users to verify their location within the filesystem. This is particularly useful for navigation or when orchestrating commands that involve the filesystem, as it provides a clear context of where you are working.

The other options serve different purposes: "cd" is used to change directories, "su" allows users to switch to another user account (typically the root user, depending on the syntax), and "ll" is commonly an alias for "ls -l," used to list files in a directory with detailed information. Each of these commands has its own specific function that does not pertain to displaying the current location within the filesystem.
