cURL posting

I want to learn how to post here using cURL, I'm trying, but nothing works. The tutorial says that I need a name, value and type fields for the form, but 4chan has only type and value;
<input type="submit" value="Reply"
or am I looking the the wrong place?
It's going to be something like this, right?
curl -d "meiru=test&something=%20Reply%20" http://dis.4chan.org/read/prog/1244389238
Please give me any clues.
