How do you display the current working directory in Linux?

To display the current working directory in Linux, the most appropriate command is pwd, which stands for "print working directory." This command outputs the full path of the directory you are currently located in within the file system. It is a fundamental command used frequently by Linux users to understand their current location in the directory structure.

The other commands listed serve different purposes:

• The ls command is used to list files and directories in the current directory, providing information about what is present but not about the directory you are currently in.

• The cd command is used to change directories, so while it influences your current working directory, it does not display its path.

• The dir command, like ls, lists the contents of a directory but does not provide the current directory's path.

Thus, the pwd command is the best suited for displaying your current working directory in Linux.
