### Set legal hold on an object

PutObject API allows setting legal hold using `x-amz-object-lock-legal-hold` header.

```sh
aws s3api put-object --bucket testbucket --key legalhold --object-lock-legal-hold-status ON --body /etc/issue
```

See <https://docs.aws.amazon.com/AmazonS3/latest/dev/object-lock-overview.html> for AWS S3 spec on object locking and permissions required for specifying legal hold.
