I need to move a large file from a Unix server to a cloud storage service. The service doesn't provide any FTP or API to upload files. The only way to upload a file is to authenticate (username and password) and complete a simple form:

Once authenticated, to upload and submit the file I need to
- Fill a compulsory form (
Enter delivery email address(es)) - Click on
Browse... - Locate the file in my computer file system
- Click the big
Sendbutton
Would that be possible from command line with cURL?
