title: in vim with xclip, yank to clipboard
body: <p>I have vim 7.2 (-clipboard -xterm_clipboard ...) in Ubuntu. You can see that it's not support clipboard. So I want to write little vim script which copies visual selected text into the clipboard using xclip tool.</p>
  
  <p>You know xclip tool works like that:</p>
  
  <pre><code>echo 'hello' | xclip -selection clipboard      #it copies 'hello' into clipboard
  </code></pre>
  
  <p>And vim can run shell commands, so I want to copy visual selected text to where instead of 'hello', But I don't know how to combine xclip and vim. Can you help me to implement it.</p>
  
  <p>Thanks for your time!</p>
