How do you remove a directory that is not empty?

The best way to remove a directory that is not empty is by using the rm -r command. This command stands for "remove recursively" and allows you to delete a directory along with all of its contents, including any subdirectories and files it may contain. The recursive option (-r) is essential in this case because the standard rm command requires this modifier when trying to delete directories rather than just files.

The rmdir command is intended only for removing empty directories, which is why it would not work for a directory that contains files or other directories. The mention of a "delete" command may imply a different context since standard Linux does not have a command called "delete"; instead, file and directory manipulation relies heavily on commands like rm and rmdir. The clear command is unrelated to file and directory management; it simply clears the terminal screen for better visibility.

Therefore, the rm -r command is the appropriate choice for removing a non-empty directory in Linux.
