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

The command used to display the current working directory in Linux is 'pwd', which stands for "print working directory." When executed, this command outputs the full path of the directory you are currently in within the filesystem. Understanding your current location in the directory structure is crucial for effective navigation and file management in Linux environments.

The other commands serve different purposes: 'dir' is used to list the contents of a directory but does not indicate your current position within it. 'ls' lists directory contents as well, showing files and folders within a specified directory rather than the user's present location. Lastly, 'cd' is the command used to change directories, but it does not display the current working directory. Therefore, 'pwd' is the appropriate command for revealing your current directory.
