-v shows all details of HTTP request and response.

-I Only response headers (HEAD request)\
      \*\*Capital i....

-i Both headers and response body. (HTML code)

Difference between i and I is that -I sends a HEAD request while -i sends any request we specify and prints the headers as well.

-H Set request headers.

-A Set User-Agent

**Example:**  Use -A to change the User-Agent, along with -I and -A to ensure the changes actually took place.
