within my bash script I have a line that looks like this:

JOB_RESULTS=$(curl --fail -k -H "Content-Type: application/xml" --write-out HTTP_CODE='%{http_code}' "${request_url}")

This line outputs the following:

{"name":"callCLF010Job","id":11693,"status":"STARTING","message":"The job has started.","exitCode":"exitCode=UNKNOWN;exitDescription="}HTTP_CODE=200

The problem is, I want to add the HTTP_CODE into the JSON message.

Is there a way to make the return look like {"name":"callCLF010Job","id":11693,"status":"STARTING","message":"The job has started.","exitCode":"exitCode=UNKNOWN;exitDescription=","HTTP_CODE":"200"}

EDIT:

With confettis changes my code looks like this:

http_code="${JOB_RESULTS:${#JOB_RESULTS}-17}"
http_body="${JOB_RESULTS:0:${#JOB_RESULTS}-17}"
http_code_json=", ${http_code}}"
my_result="${http_body/%\}/$http_code_json}"

when I run echo $my_result my output looks like this:

{"name":"callCLF010Job","id":11702,"status":"STARTING","message":"The job has started.","exitCode":"exitCode=UNKNOWN;exitDescriptio

One option is to use sed to format the output the way you want:

echo $JOB_RESULTS | sed 's/}HTTP_CODE=\([0-9]\+\)$/,"HTTP_CODE":"\1"}/'

Or inside your command:

JOB_RESULTS=$(curl --fail -k -H "Content-Type: application/xml" --write-out HTTP_CODE='%{http_code}' "${request_url}" | sed 's/}HTTP_CODE=\([0-9]\+\)$/,"HTTP_CODE":"\1"}/')

I want to be able to use jq to grab the code, for example: http_status=$(echo "${JOB_RESULTS}" | jq -r '.HTTP_CODE')
I see that this formats the output, but what I want is to actually insert HTTP_CODE into the $JOB_RESULTS, so that if I echo'd just $JOB_RESULTS HTTP_CODE would appear there
In this case you can use sed inside your command. I edited the answer to show you.
Thank you so much @Murilo Dutra, that was very simple and exactly what I needed

This is using shell parameter expansion to get the job done. (Pure bash, besides curl.)

curlout=$(curl -s --fail -k -H "Content-Type: application/xml" --write-out '"HTTP_CODE":"%{http_code}"' "http://example.com")
http_code="${curlout:${#curlout}-17}"
http_body="${curlout:0:${#curlout}-17}"
http_code_json=", ${http_code}}"
my_result="${http_body/%\}/$http_code_json}"

Replace http://example.com with the URL or variable of your choice.

In order to prevent errors in case of a wrong URL or (no) output, you should put the last four lines within an if-construct. E.g. if [[ $http_code != '"HTTP_CODE":"000"' ]].

Are you sure this will work? my_result is missing some quotations and brackets, I'm not sure how you want this formatted. I want to be able to use jq to parse HTTP_CODE from the response
@Josh I'm sorry, I've had two stupid typos in my answer. I've edited it, please try it again now. echo $my_result | jq .HTTP_CODE does now print "200" for me. If you need a numeric value let me know then I can edit my answer accordingly.
I'm not sure what you edited, http_code_json seems to have an extra bracket, and for some reason the -17 in http_body is red highlighted in my vim syntax
I'll keep trying for now, you seem very close to what I'm looking for Thank you
@Josh I've had an = in my original answer for the JSON when it has to be a :. I tried my answer with http://a.4cdn.org/boards.json instead of http://example.com and it works flawlessly.
