Used to delete empty directories.
The rmdir command is used to delete empty directories. When a directory is no longer in use, or when disk space reaches its limit, directories that have lost their value need to be deleted. The rmdir command can delete one or more empty subdirectories from a directory. The command deletes one or more subdirectories, where dirname represents the directory name. If no path is specified in dirname, the directory named dirname in the current directory is deleted; if dirname contains a path, the directory at the specified location is deleted. To delete a directory, you must have write permission for its parent directory.
Note: A subdirectory must be empty before it is deleted. This means all files in that directory must be removed using the rm command first. Additionally, the current working directory must be above the directory being deleted; it cannot be the directory itself or a subdirectory of it.
Although the rm command with the -r option can be used to recursively delete all files in a directory and the directory itself, doing so is very dangerous.
rmdir(options)(parameters)
-p or --parents: After deleting the specified directory, if its parent directory also becomes empty, delete it as well.
--ignore-fail-on-non-empty: This option causes the rmdir command to ignore error messages resulting from attempting to delete a non-empty directory.
-v or --verbose: Displays detailed information during command execution.
--help: Displays help information for the command.
--version: Displays version information for the command.
Directory list: A list of empty directories to be deleted. When deleting multiple empty directories, separate the directory names with spaces.
Delete the subdirectory named www in the current directory:
rmdir www
Delete the subdirectory named Test in the www directory of the current directory. If www becomes empty after Test is deleted, www is also deleted.
rmdir -p www/Test
The following command is equivalent to rmdir a/b/c, rmdir a/b, rmdir a:
rmdir -p a/b/c
