-w, --write-out <format>
              Make curl display information on stdout after a completed transfer. The format is a string that may contain plain text mixed with any number of variables. The
              format can be specified as a literal "string", or you can have curl read the format from a file with "@filename" and to tell curl  to  read  the  format  from
              stdin you write "@-".

              The  variables  present in the output format will be substituted by the value or text that curl thinks fit, as described below. All variables are specified as
              %{variable_name} and to output a normal % you just write them as %%. You can output a newline by using \n, a carriage return with \r and a tab space with \t.

              The output will be written to standard output, but this can be switched to standard error by using %{stderr}.

              NOTE: The %-symbol is a special symbol in the win32-environment, where all occurrences of % must be doubled when using this option.

% content_type   The Content-Type of the requested document, if there was any.

% filename_effective   The ultimate filename that curl writes out to. This is only meaningful if curl is told to write to a file with the  -O,  --remote-name  or  -o, --output option. It's most useful in combination with the -J, --remote-header-name option. (Added in 7.26.0)'

% ftp_entry_path The initial path curl ended up in when logging on to the remote FTP server. (Added in 7.15.4)

% http_code      The  numerical  response  code  that was found in the last retrieved HTTP(S) or FTP(s) transfer. In 7.18.2 the alias response_code was added to show the same info.

% http_connect   The numerical code that was found in the last response (from a proxy) to a curl CONNECT request. (Added in 7.12.4)

% http_version   The http version that was effectively used. (Added in 7.50.0)

% local_ip       The IP address of the local end of the most recently done connection - can be either IPv4 or IPv6 (Added in 7.29.0)

% local_port     The local port number of the most recently done connection (Added in 7.29.0)

% num_connects   Number of new connects made in the recent transfer. (Added in 7.12.3)

% num_redirects  Number of redirects that were followed in the request. (Added in 7.12.3)

% proxy_ssl_verify_result   The result of the HTTPS proxy's SSL peer certificate verification that was requested. 0  means  the  verification  was  successful.  (Added  in 7.52.0)'

% redirect_url   When an HTTP request was made without -L, --location to follow redirects (or when --max-redir is met), this variable will show the actual URL a redirect would have gone to. (Added in 7.18.2)

% remote_ip      The remote IP address of the most recently done connection - can be either IPv4 or IPv6 (Added in 7.29.0)

% remote_port    The remote port number of the most recently done connection (Added in 7.29.0)
