How to send line break with curl?

Question

I\'ve tried the following to send a line break with curl, but \\n is not interpreted by curl.

curl -X PUT -d \"my message\\n\" http://localhost:         


        

Answer 1

The solution for someone who doesn't want to use files, and doesn't want to resort to shell escaping magic is:

curl -X POST --data-binary @- http://url.com <

But this is literal newlines in the post data payload, and not in form fields.
