sync

The aws s3 sync command is used to synchronize the contents of a bucket and a directory, or two buckets. This command compares the source and the destination, only copying the files that have been modified or added in the source. It's an efficient way to ensure that your local files and S3 bucket have the same content.

aws s3 sync /local/path s3://bucketname/path/
