How to display request headers with command line curl

Question

Command line curl can display response header by using -D option, but I want to see what request header it is sending. How can I do that?

Answer 1

The verbose option is handy, but if you want to see everything that curl does (including the HTTP body that is transmitted, and not just the headers), I suggest using one of the below options:

• --trace-ascii - # stdout
• --trace-ascii output_file.txt # file
