long: url Arg: <url> Help: URL to work with --- Specify a URL to fetch. This option is mostly handy when you want to specify URL(s) in a config file. If the given URL is missing a scheme name (such as "http://" or "ftp://" etc) then curl will make a guess based on the host. If the outermost sub-domain name matches DICT, FTP, IMAP, LDAP, POP3 or SMTP then that protocol will be used, otherwise HTTP will be used. Since 7.45.0 guessing can be disabled by setting a default protocol, see --proto-default for details. This option may be used any number of times. To control where this URL is written, use the --output or the --remote-name options.
