-o ... -w ... for Effective Return CodeSometimes you want to get the HTTP response code before you decide
to do something with what you downloaded using curl —
especially if the response code is anything but 200 (meaning you
probably didn’t download what you wanted. By separating the output
with -o you can use -w %{response_code} to print the numeric code to
standard out and exam that easily in a condition.
curl -sSL 'https://raw.githubusercontent.com/rwxrob/k8sapp-nfd/master/in/check' -o /tmp/foo -w '%{response_code}'
