AWS CLI S3 usage examples

• Local dir to remote bucket sync
• Local dir to remote bucket copy with gzip content encoding header
• Remote to remote bucket copy

Local dir to remote bucket sync

$ aws s3 sync \
  --dryrun \
  --region REGION_NAME \
  --delete \
    /path/to/files/ \
    s3://BUCKET_NAME/path/to/dest

Local dir to remote bucket copy with gzip content encoding header

$ aws s3 cp \
  --dryrun \
  --region REGION_NAME \
  --recursive \
  --content-encoding 'gzip' \
    /path/to/files/ \
    s3://BUCKET_NAME/path/to/dest

Remote to remote bucket copy

$ aws s3 cp \
  --dryrun \
  --region REGION_NAME \
  --recursive \
    s3://BUCKET_NAME_SOURCE/path/to/source \
    s3://BUCKET_NAME_TARGET/path/to/dest

That's correct - credentials come from either ~/.aws/credentials (controlled by --profile) or environment variables are the other choice.

You never give these keys over the CLI itself, nor is it even possible - since these things could be captured by other processes way too easily.
