Which command is used to delete all files in the current directory as well as all files and sub-directories in its subdirectories ?
Correct answer: B. rm -r *
- A. rm *
- B. rm -r *
- C. rm all
- D. rm *.*
Explanation
`rm -r *` recursively removes the non-hidden entries in the current directory, including their files and subdirectories. Plain `rm *` does not remove directories because it lacks the recursive option.
