If you are uploading for the first time, you can set the files to be public on upload on the command line:

aws s3 sync . s3://my-bucket/path --acl public-read

As documented in Using High-Level s3 Commands with the AWS Command Line Interface

Unfortunately it only applies the ACL when the files are uploaded. It does not (in my testing) apply the ACL to already uploaded files.

If you do want to update existing objects, you used to be able to sync the bucket to itself, but this seems to have stopped working.

[Not working anymore] This can be done from the command line:

aws s3 sync s3://my-bucket/path s3://my-bucket/path --acl public-read

(So this no longer answers the question, but leaving answer for reference as it used to work.)
