title: How to make 10,000 files in S3 public
body: <p>I have a folder in a bucket with 10,000 files. There seems to be no way to upload them and make them public straight away. So I uploaded them all, they're private, and I need to make them all public.</p>
  
  <p>I've tried the aws console, it just gives an error (works fine with folders with less files).</p>
  
  <p>I've tried using S3 organizing in Firefox, same thing.</p>
  
  <p>Is there some software or some script I can run to make all these public?</p>
