How can you safely create a nested directory path logs/2024/march in Ruby, ensuring all intermediate directories are created?
ADir.mkdir('logs/2024/march')
BFileUtils.mkdir_p('logs/2024/march')
CDir.mkdir('logs') && Dir.mkdir('2024') && Dir.mkdir('march')
DDir.create('logs/2024/march')

  2. Final Answer:

    FileUtils.mkdir_p('logs/2024/march') -> Option B

  3. Quick Check:

    Use FileUtils.mkdir_p for nested dirs [OK]
Quick Trick: FileUtils.mkdir_p creates nested directories safely [OK]
Common Mistakes:
  • Using Dir.mkdir for nested paths
  • Trying to chain Dir.mkdir without paths
