A simple alias for pulling out headers for HTTP requests

curl_headers

#!/bin/bash
if [ -z $1 ];
then echo "Missing url, try $0 http://example.com";
else
curl -v -s $1 1> /dev/null
fi
## based on https://lornajane.net/posts/2014/view-only-headers-with-curl

put it in somewhere like ~/bin/curl_headers then make it executable chmod +x ~/bin/curl_headers

then use it like

curl_headers https://google.com
