-X/--request <command>

(HTTP) Specifies a custom request method to use when communicating with the HTTP server. The specified request will be used instead of the method otherwise used (which defaults to GET). Read the HTTP 1.1 specification for details and explanations. Common additional HTTP requests include PUT and DELETE, but related technologies like WebDAV offers PROPFIND, COPY, MOVE and more.

(FTP) Specifies a custom FTP command to use instead of LIST when doing file lists with FTP.

If this option is used several times, the last one will be used.
