Does AWS CLI upload files larger than 4GB to Amazon Glacier?

Question

The AWS Command Line Interface (CLI) allows to upload a file to AWS Glacier. But there is also a limit of 4GB for file uploads in the AWS Rest API. If I need to upload a file larger than 4GB through the Rest API, I need to use the multi-part upload.

My question is: does the AWS CLI handle internally file uploads larger than 4GB, or do I need to handle myself the multipart upload when handling files larger than 4GB? Can I just pass a 20Gb file to the upload-archive option of the AWS CLI and it will just work? If the CLI can't handle large file uploads directly, there is any command line tool that does it for me (freeing me from the trouble of implementing all of the checksum computing, error handling and retry logic when a part upload fails)?

I understand that the 4GB limit is on the AWS Rest API, but I could not find anything about how this limit is handled in the CLI. I could just make the test, but my upload speed is not so fast and I fear wasting a few hours before discovering that it does not work.

I'm using glacier-cmd (https://github.com/uskudnik/amazon-glacier-cmd-interface), works pretty well, but seems to be unsupported recently. Sometimes it has a timeout with big files (~50GB).
