How to capture all the HTTP requests of a website using shell script?

As a web application tester I need to verify the http requests(seen in the net tab of the firebug when you hit a site in firefox) for my web site.

Is there a way to capture the http requests/network calls in shell scripting?

I have solution to do it in Java. We can use browsermob proxy.

But please help me how to do in shell scripting.
