S3: make a public folder private again?

Question

How do you make an AWS S3 public folder private again?

I was testing out some staging data, so I made the entire folder public within a bucket. I\'d like to restrict it

If you want a delightfully simple one-liner, you can use the AWS Powershell Tools. The reference for the AWS Powershell Tools can be found here. We'll be using the Get-S3Object and Set-S3ACL commandlets.

$TargetS3Bucket = "myPrivateBucket"
$TargetDirectory = "accidentallyPublicDir"
$TargetRegion = "us-west-2"

Set-DefaultAWSRegion $TargetRegion

Get-S3Object -BucketName $TargetS3Bucket -KeyPrefix $TargetDirectory | Set-S3ACL -CannedACLName private
