Curl Show Response Headers | Commands & Smart Replies In 2026

Top alternatives: curl response headers, curl headers only, curl show headers, curl HTTP headers, curl display response headers

Ever run a curl command and think, “Okay, but what did the server actually send back?” When debugging APIs, checking redirects, testing websites, inspecting caching, or troubleshooting authentication, seeing the response headers can be incredibly useful. The right curl option lets you quickly inspect things like the HTTP status, content type, server information, cookies, redirects, and caching headers without digging through a browser’s developer tools.

Whether you are working in a terminal, testing an API, checking a website response, or simply learning curl, knowing how to display response headers can save time. In this guide, you will find practical commands, concise explanations, and easy examples for different situations. Think of it as your quick reference whenever you need curl to stop hiding the useful stuff and show you exactly what the server returned.

FAQs

What Does “Curl Show Response Headers” Mean?

It means using curl to display the HTTP headers returned by a server. These headers can include status information, content type, caching details, cookies, redirects, and other metadata.

How Do I Show Response Headers With Curl?

Use curl -i URL when you want the response headers displayed together with the response body.

How Do I Show Only Response Headers?

Use curl -I URL when you want headers without the normal response body. This is commonly useful for quick checks.

What Does `curl -D -` Do?

The -D option writes response headers to a destination. Using - as the destination sends those headers to standard output.

What Is The Difference Between `-i` And `-I`?

The lowercase -i includes headers in the normal response output, while uppercase -I is used to request headers without the normal response body.

Conclusion

Knowing how to inspect HTTP response headers with curl can turn frustrating debugging sessions into much simpler investigations. Instead of guessing why an API behaves differently, you can look directly at the information the server sends back. Whether you use -i for headers and body, -I for a headers-focused request, or -D when you want to capture headers separately, each option has a useful place in your workflow.

The trick is choosing the command that matches what you actually need. Save this guide for your next API or web debugging session, share it with your developer friends, and keep these commands handy. Once you start checking headers regularly, HTTP debugging gets a whole lot easier.
