  <p>I'm trying to uninstall a single version of ruby. The second in this list:</p>
  
  <pre><code>which -a ruby
  /Users/snowcrash/.rvm/rubies/ruby-1.9.2-p318/bin/ruby
  /Users/snowcrash/.rvm/bin/ruby
  </code></pre>
  
  <p>However, when I run:</p>
  
  <pre><code>rvm remove
  </code></pre>
  
  <p>I get: </p>
  
  <pre><code>Really? remove all? See "rvm list known" and limit the selection to something more sane please :)
  </code></pre>
  
  <p>So, running: </p>
  
  <pre><code>rvm list known 
  </code></pre>
  
  <p>shows a whole list of versions. However, none of these is the one I want to delete, i.e. /Users/snowcrash/.rvm/bin/ruby</p>
  
  <p>E.g. </p>
