How to delete files recursively from an S3 bucket

Question

I have the following folder structure in S3. Is there a way to recursively remove all files under a certain folder (say foo/bar1 or foo or foo/bar2/1 ..)

Answer 1

In case using AWS-SKD for ruby V2.

s3.list_objects(bucket: bucket_name, prefix: "foo/").contents.each do |obj|
  next if obj.key == "foo/" 
  resp = s3.delete_object({
    bucket: bucket_name,
    key: obj.key,
  })
end

attention please, all "foo/*" under bucket will delete.
