Which command displays the current working directory?

The command that displays the current working directory is "pwd," which stands for "print working directory." When executed, it shows the full path of the directory you are currently in within the filesystem. This is particularly useful for users to determine their location in the directory structure, especially when navigating through multiple directories.

The other options serve different purposes: "getcwd" is a system call that retrieves the current working directory in programming contexts but is not directly used in the shell as a command. "ls" lists files and directories in the current directory but does not indicate which directory is currently being accessed. "cd" is used to change directories rather than display the directory you are currently in.
