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

The command used to display the current directory in Linux is "pwd," which stands for "print working directory." When this command is executed, it outputs the full path of the directory the user is currently located in. This is especially useful for users who navigate through different directories and need to keep track of their current location within the filesystem.

While other commands are also useful in a Linux environment, they serve different purposes. For example, "ls" lists the files and directories within the current directory but does not reveal the path of the current directory itself. The "cd" command is used to change the current directory rather than display it. Lastly, "dir" is a command that can list the contents of directories as well, but it is more commonly associated with DOS/Windows systems rather than native Linux commands. Hence, "pwd" is the appropriate choice for displaying the current directory's path in a Linux terminal.
