To Replace Curl-i Header and Body in a Shell Script

curl-i seems to yield the following output:

status code
header
header
header

body
body
body

I would like to use this first \n\n as a boundary and eventually get the output similar to the following:
What should I do?

body
body
body

status code
header
header
header

If possible, I would appreciate it if you could use one liner (like connecting it with a pipe).

The following is an example of how to use awk, where RS(Record Separator) is set to the HTTP response header and the response body delimiter string (\r\n\r\n).

$curl-s-i https://example.com/ |awk-vRS='\r\n\r\n' 'NR==1 {first=$0}NR>1;END {printfirst}'
<!doctype html>
<html>
<head>
    <title>Example Domain</title>
                :

</body>
</html>

Anyway, I wrote it down.Maybe I can write better.

$cathoge.txt
status code
header
header
header

body
body
body
$ cathoge.txt | awk'/^$/{f=1; next}; { if(!f){d=d$0"\n"} else {print}}};END {printf"\n"d}'
body
body
body

status code
header
header
header

I also wrote it on sed.

$cathoge.txt | sed-e'1, /^$/{/^$/d;H;d}'-e'$G'
body
body
body

status code
header
header
header
