What 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 this command is executed, it shows the full path to the directory in which the user is currently located. This is particularly useful for users who navigate through various directories and need to confirm their current location within the filesystem.

The cd command is used to change the current directory; it does not display the current directory. The ls command lists the files and directories within the current directory, providing visibility into its contents but not its location. The dir command, while it can be used in some Linux environments to list directory contents as well, is more commonly associated with DOS and Windows systems; it's not the standard command for displaying the current working directory in Linux. Therefore, pwd is clearly the correct choice for retrieving the current working directory.
