title: RSync on save in VIM
body: <p>I'm looking for a way to map the :w command so that when I use it, it will rsync the current directory and save the file in question. Ideally, the response generated by the rsync command should be returned in vim, but not in the the current file, but rather as a tooltip or something.</p>
  <p>I managed to achieve this in TextMate and am now looking to start working with Vim.
  I've been trying things like <code>:map w :w|!rsync</code>, but that doesn't seem to work.</p>
