How do I upload files to S3 without the console?

The four ways

• The AWS CLI, the command line. One command copies a file or syncs a whole folder, splits big files into pieces and retries the ones that fail. A single file can be up to 5 TB.
• A presigned POST, an upload form on a web page, or an upload link. Lets an outsider send a file straight to the bucket with no Amazon access, with size limits built in.
• AWS Transfer Family, SFTP in front of the bucket, for partners who expect it.
• A workspace with uploads built in, where drag and drop lands in the right folder under the person’s own sign-in.
