Overview of rmdir
`rmdir` command is used to remove empty directories located in the current directory or specified path. It is useful for cleaning up the file system and removing unnecessary empty folders. However, if the directory is not empty, you should use `rm -r` (forced deletion) instead of `rmdir`.
Main Functions of rmdir
`rmdir` command is primarily used for the following purposes:
Key Use Cases
- Cleaning Empty Directories: Removes empty folders that are no longer needed or completed projects to keep the file system clean.
- Automated Scripts: Used to clean up empty temporary directories created under specific conditions (e.g., after all log files have been processed).
`rmdir` vs `rm -r`
`rmdir` and `rm -r` are used to delete directories, but there are important differences.
Command Comparison
- `rmdir`: Deletes **only empty directories**. If the directory is not empty, an error occurs. It is used safely to remove only empty directories.
- `rm -r` (or `rm -rf`): Recursively deletes **all contents** even if there are files or subdirectories within the directory. It is a very powerful command, so extreme caution is needed to avoid accidentally deleting important data.

rmdir non_empty_dirIf there are files in `non_empty_dir`, `rmdir` will output an error message and will not delete the directory.
Delete Nested Empty Directories at Once
mkdir -p parent_dir/child_dir/grandchild_dir
rmdir -p parent_dir/child_dir/grandchild_dirIn an empty directory structure named `parent_dir/child_dir/grandchild_dir`, after deleting `grandchild_dir`, it will also delete `child_dir` and `parent_dir` if they are empty.
Check Detailed Directory Deletion Process
mkdir -p temp_data/sub1/sub2
rmdir -pv temp_data/sub1/sub2Checks the process of deleting `temp_data` directory and its parent directories with detailed messages.
Find and Delete Empty Directories with `find` and `rmdir`
find . -type d -empty -deleteYou can use the `find` command in combination to find and delete all empty directories across the system or a specific path. This command recursively searches from the current directory (`.`) to find and delete empty directories. **Warning: Use with caution.**
