title: Find and Replace text in .sql files
body: <p>I have many <code>.sql</code> files in subfolders. I am presently manually opening them up, and searching for <code>OLDSERVERNAME</code>, and replacing it with <code>NEWSERVERNAME</code>(I'm doing migration). There must be a faster way to do this. I tried using FART, but I guess I wasn't doing it right. </p>
  
  <p>This is what I tried(in main folder):</p>
  
  <pre><code>fart -i -p -c *.sql OLDSERVERNAME NEWSERVERNAME
  </code></pre>
  
  <p>Can I perhaps use unix utilities for this purpose?  </p>
