Which command is used to display the current working directory?

The command that displays the current working directory is "pwd," which stands for "print working directory." When you execute this command in a terminal or command line interface, it outputs the full path of the directory you are currently in. This is particularly useful for users who navigate through various directories and want to confirm their present location within the filesystem.

The other commands, while relevant in the context of directory management, serve different purposes. For example, "dir" is used to list the contents of a directory in some operating systems, notably DOS and Windows environments, but it does not show the current working directory. The "cd" command is employed to change the directory, allowing users to navigate through the filesystem, but it does not provide any information about the current directory itself. Lastly, "ls" is a command used primarily on Unix-based systems to list files and directories within the current working directory, but again, it does not indicate the path of the directory you are currently working in. Therefore, "pwd" is the specific command needed to fulfill the requirement of displaying the current working directory.
