Learn about the commands in linux today: rmdir command . rmdir is a commonly used command. The function of this command is to delete empty directories . A directory must be empty before it is deleted. (Note that the rm -r dir command can be used in place of rmdir, but it is very dangerous.) When deleting a directory, you must also have write permission to the parent directory.
