Is there a shell command to see the headers of a HTTP request?

For example, I would like to know what the headers retrieved from are

How can I do this?

In order to retrieve only the header, give this a try:

curl -I

From the man page:

(HTTP/FTP/FILE) Fetch the HTTP-header only! HTTP-servers feature the command HEAD which this uses to get nothing but the header of a document. When used on a FTP or FILE file, curl displays the file size and last modification time only.

Also, -D <file> will save the headers to a file. –  coredump Mar 20 '11 at 16:02

Use wget for instance

wget -O - -o /dev/null --save-headers

yes, but i don't want to save the page on my pc.....i only want to see the headers –  Damiano Mar 20 '11 at 10:22
You won't save it with this command –  Dmytro Leonenko Mar 20 '11 at 11:01
Yup, you're just filling /dev/null :p -O - writes the headers to the stdout ("the console") –  Lekensteyn Mar 20 '11 at 16:00

You can do that with curl:

curl -i ''


HTTP/1.0 302 Found
Server: BigIP
Connection: Keep-Alive
Content-Length: 0

(for some reason, IANA decided to redirect, result: no body)

curls manual page about the -i option:


(HTTP) Include the HTTP-header in the output. The HTTP-header includes things like server-name, date of the document, HTTP-version and more...

You can see them with curl.

Or you can use HEAD The result is very similar to that produced by curl -i '' although it seems to return more headers.
