title: Unrar all file in directory without prompting
body: <p>I tried:</p>
  
  <pre><code>find . -name "*.rar" -exec unrar x -o {} \;
  </code></pre>
  
  <p>Output:</p>
  
  <blockquote>
    <p>Extracting from ./setup.part2.rar</p>
    
    <p>Extracting from ./setup.part1.rar</p>
    
    <p>RORY/nsfw.zip already exists. Overwrite it ? [Y]es, [N]o, [A]ll,
    n[E]ver, [R]ename, [Q]uit A</p>

  <p>I can't have this prompting me; both hands occupied unfortunately. thought the -o flag would do it, but nope.</p>
