Scenario

The /tmp directory has accumulated numerous leftover folders from previous application runs and temporary scripts. Many of these directories are now empty and can be safely removed.

Task

Write a command or short script that searches through /tmp, finds all empty directories recursively, and deletes them without affecting any directories that contain files or subdirectories.

Example

# Before (empty directories present)

/tmp/old_build_cache/
/tmp/session_temp_1234/
/tmp/extract_workspace/
/tmp/app_tmp_5678/
/tmp/active_project/file.txt

# After (empty directories removed)

/tmp/active_project/file.txt

Step 1: Preview empty directories before deletion.

find /tmp -type d -empty

Step 2: Count how many empty directories exist.

find /tmp -type d -empty | wc -l

Step 3: Delete all empty directories using -delete.

find /tmp -type d -empty -delete

Step 4: Verify empty directories were removed.

find /tmp -type d -empty | wc -l
