rmdir [OPTION]... DIRECTORY...

The rmdir command removes empty directories.
Important characteristics of rmdir:
• Only removes empty directories that contain no files or subdirectories.
• Processes directories in the order specified
• Fails if the directory contains any files or subdirectories
• Does not remove files (use rm for files)

Common options:
• -p or --parents: Remove parent directories if they become empty
• -v or --verbose: Display what is being removed
• --ignore-fail-on-non-empty: Ignore failures due to non-empty directories

• Removing a single empty directory:
  

  $ rmdir folder1
  

  The directory must be empty, otherwise you will get: "rmdir: failed to remove 'folder1': Directory not empty".
  
  
• Removing multiple empty directories:
  

  $ rmdir folder1 folder2 folder3
  

  All specified directories must be empty for the command to succeed.
  
  
• Removing nested directories (subdirectories first):
  

  $ rmdir folder/folder1 folder/folder2 folder
  

  The child directories must be removed before the parent directory.
  
  
• Using the -p option to remove parent directories:
  

  $ rmdir -p folder/folder1
  

  This removes both folder1 and folder if folder becomes empty after removing folder1.
  
  
• Using verbose mode:
  

  $ rmdir -v folder1 folder2
  

  This will display messages showing which directories are being removed.
  
  
• For non-empty directories, use rm -r to remove directories and their contents recursively. Be careful with this command as it permanently deletes files and directories.
