Usage:

response_code=$(kurl -X GET https://httpstat.us/400)
if [ "$HTTP_CODE" -ne 200 ]; then
	echo "Error in response: $HTTP_CODE"
    exit 1
fi
echo "response body: $response_code"

My assumptions:

  • While scripting, I care more about correctness and ease of writing than perf or anything else
  • We rarely write concurrent code in bash so it's safe use global vars
