cUrl Misc



Is there a way to follow redirects with command line cURL
curl -L <URL>

curl -i -v -k url

Dump response header
--dump-header headers.txt

url has a specific option, --write-out, for this:
$ curl -o /dev/null --silent --head --write-out '%{http_code}\n' <url>
200
  • -o /dev/null throws away the usual output
  • --silent throws away the progress meter
  • --head makes a HEAD HTTP request, instead of GET
  • --write-out '%{http_code}\n' prints the required status code

I haven't tested this on a 500 code, but it works on others like 200, 302 and 404.
response=$(curl --write-out %{http_code} --silent --output /dev/null servername)
