title: How can I search and replace recursively in a directory in Vim?
body: <p>I found out about Vim's substitute command...</p>
  
  <pre><code>:%s/replaceme/replacement/gi
  </code></pre>
  
  <p>And vimgrep...</p>
  
  <pre><code>:vimgrep  /findme/gj  project/**/*.rb
  </code></pre>
  
  <p>Is there a way to combine them in order to do a replacement across all the files under a directory?</p>
