s3 change permissions recursively

I have an s3 bucket that contains hundreds of files within subfolders. I know that a small number of those files have public read permissions but I don't know which files they are.

I'd like to remove those permissions from all files so I need to either apply a new set of permissions recursively to all files in the bucket or list all files with public read permissions.

You can copy the files to themselves (that is, overwrite themselves) while changing permissions.

It might involve adding a small change (eg adding some metadata) to allow the copy to happen:

aws s3 cp s3://my-bucket/ s3://my-bucket/ --recursive --acl bucket-owner-full-control --metadata "One=Two"

See: Amazon S3 File Permissions, Access Denied when copied from another account
