How to use the rmdir command under Linux

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 replace rmdir, but it is very dangerous.) When deleting a directory, you must also have write permissions on the parent directory.

1. Command format:
rmdir [option]... Directory...

2． Command function:
This command deletes one or more subdirectory items from a directory. When deleting a directory, you must also have write permissions on the parent directory.

3. Command parameters:
-p Recursively delete the directory dirname. When the subdirectory is deleted and its parent directory is empty, it will also be deleted. If the entire path is deleted or part of the path is retained for some reason, the system displays the appropriate information on standard output.
-v, --verbose Display the command execution process
4． Command example:
Example 1: rmdir cannot delete non-empty directories
