title: Forcing a copy with a Thor action
body: <p>I'm using the Thor built-in action "copy_file" to copy a file from my template source, overwriting an existing file.</p>
  
  <p>I always want to overwrite, and don't want to have to confirm this interactively.</p>
  
  <p>The documentation doesn't suggest there is a force option in the config hash for this action, but <a href="http://textmate.rubyforge.org/thor/Thor/Actions.html" rel="nofollow">http://textmate.rubyforge.org/thor/Thor/Actions.html</a> does indicate that config[:behavior] can be set to force, but I can't see how to do this.</p>
  
  <p>If anyone has an example of doing this that they could share, I'd be most grateful.</p>
  
  <p>Thanks.</p>
