rmdir - Command in Linux

Complete Guide for Learners and Professionals

The rmdir command in Linux is a straightforward yet essential tool for managing directories. It is specifically designed to remove empty directories only. While it may seem basic at first glance, understanding its use cases, options, limitations, and integration with other commands can significantly enhance your Linux command-line proficiency.

What is rmdir?

rmdir stands for Remove Directory. It is used to delete empty directories from the Linux file system. Unlike rm -r, it does not remove directories that contain files or subdirectories, making it a safer and more cautious choice in many situations.

Syntax:

rmdir [OPTION]... DIRECTORY...

Examples of rmdir Usage

1. Removing a Single Empty Directory

mkdir sample
rmdir sample

Explanation: mkdir creates a new directory named sample. rmdir then removes it because it is empty.

2. Attempting to Remove a Non-Empty Directory

mkdir myfolder
touch myfolder/file.txt
rmdir myfolder

Explanation: touch creates an empty file inside myfolder. rmdir will fail with an error since the directory is no longer empty.

3. Removing Nested Empty Directories

mkdir -p a/b/c
rmdir -p a/b/c

Explanation: mkdir -p creates parent and child directories. rmdir -p removes c, b, and a, but only if all are empty.

⚙️ Switches (Options) of rmdir

Switch	Description
-p	Removes the specified directory and its parent directories (if empty)
--ignore-fail-on-non-empty	Silently ignores the error if a directory is not empty (not standard in all distros)
--verbose or -v	Shows a message for each directory removed (on supported systems)

---

Scenarios with Each Switch

Using -p (Parent Directory Removal)

mkdir -p logs/archive/2024
rmdir -p logs/archive/2024

Explanation: Removes 2024, archive, and logs only if all are empty.

Using --verbose or -v

mkdir mydir
rmdir -v mydir

Output: rmdir: removing directory, 'mydir'

Using --ignore-fail-on-non-empty

mkdir example && touch example/file.txt
rmdir --ignore-fail-on-non-empty example

Note: No error message shown; directory remains.

---

Caution While Using rmdir

• It only works on empty directories.
• Trying to remove a non-existent directory will return an error.
• Recursive deletion is not supported; use -p only for empty nested directories.
• Not all switches (e.g., --verbose) are universally supported on every Linux distro.

---

Alternative Commands

❌ Using rm -r for Non-Empty Directories

rm -r myfolder

Warning: Removes myfolder and all its contents recursively. Use cautiously.

Using find to Delete All Empty Directories

find . -type d -empty -delete

Tip: Recursively finds and deletes all empty directories from the current directory.

---

🧠 Tips for Effective Usage

• Check if a directory is empty:

ls -A directory

Lists all contents, including hidden files. If nothing is listed, it’s empty.

• Combine with other commands in scripts:

for dir in */; do rmdir "$dir" 2>/dev/null; done

Tries to remove all top-level empty directories and suppresses errors.

• Safely clean nested empty directories:

find . -type d -empty -delete

Ideal for cleaning projects or backups without risking data loss.

---

Summary

rmdir is a simple but vital command for maintaining clean directory structures in Linux. While limited to empty directories, its options like -p and -v offer added control. In scenarios requiring more power (like deleting non-empty folders), alternatives like rm -r or find ... -delete should be used carefully.

Whether you're writing scripts, cleaning up after builds, or managing servers, mastering rmdir helps you stay precise and efficient on the command line.
