To download the bucket policy to a file, you can run:: aws s3api get-bucket-policy --bucket amzn-s3-demo-bucket --query Policy --output text > policy.json You can then modify the ``policy.json`` file as needed. Finally you can apply this modified policy back to the S3 bucket by running:: aws s3api put-bucket-policy --bucket amzn-s3-demo-bucket --policy file://policy.json
