linux中的cURL命令返回http响应代码

Question

Please i want to use the cURL command in linux OS to return as a result just the http response code which is "200" if it is okey

am using that command:

curl -I -L domain.com

but this is returning for me a full text like this

HTTP/1.1 **200** OK

so please i just need the response code and not the whole text

Regards

Answer 1

curl -s -o out.html -w '%{http_code}' http://www.example.com

Answer 2

Running the following will supress the output so you won't have any cleanup.

curl -s -o /dev/null -w '%{http_code}' 127.0.0.1:80

Example above uses localhost and port 80
