If all you want to do is get search results you only need URL encode the
"q" parameter. That said doing anything automated with google probably
violated there TOS
https://www.google.ca/search?q=cat&hl=en&num=10&lr=lang_en

Dear Weedy ,

Thanks for your great help, this method is very useful to me .
Acturely , my question is from this articule :

   http://curl.haxx.se/docs/httpscripting.html
In this articule , the section 4.2 said :
......

* The form would look very similar to the previous one:

        <form method="POST" action="junk.cgi">
          <input type=text name="birthyear">
          <input type=submit name=press value=" OK ">
        </form>

  And to use curl to post this form with the same data filled in as before, we
  could do it like:

        curl --data "birthyear=1905&press=%20OK%20"
http://www.example.com/when.cgi
......
*

So, I think that if the html element "*<input type=submit name=press
value=" OK ">* " does not contain an "*name*" attribute, like

*<input type=submit value=" OK ">
*thus, what should the curl command be ? Maybe like the following command ?
*curl --data "birthyear=1905" http://www.example.com/when.cgi*

Dose this right?

*Best Reguards to you !
Have a nice day !*

Alfred Zhang,

Shanghai, China
