get-headers GoDoc Go Report Card

Simple tool to show the headers from GET-ing a URL

The problem this solves is that when you use curl -I it does a HEAD request, potentially changing the result, and when you do curl -i it also dumps the page HTML on you. This does a GET and returns those results—including any doubled headers. It also (optionally) downloads the body of the page and returns speed and timing information.

Installation

First install Go.

If you just want to install the binary to your current directory and don't care about the source code, run

GOBIN=$(pwd) go install github.com/carlmjohnson/get-headers@latest
