Answer 1

curl -sL -w "%{http_code}\n" "http://www.google.com/" -o /dev/null

• -s = Silent cURL's output
• -L = Follow redirects
• -w = Custom output format
• -o = Redirects the HTML output to /dev/null

Example:

[~]$ curl -sL -w "%{http_code}\n" "http://www.google.com/" -o /dev/null
200

I would probably remove the \n if I were to capture the output.
