title: In Ruby, what's the easiest way to "chomp" at the start of a string instead of the end?
body: <p>In Ruby, sometimes I need to remove the new line character at the beginning of a string. Currently what I did is like the following. I want to know the best way to do this. Thanks.</p>
  
  <pre><code>s = "\naaaa\nbbbb"
  s.sub!(/^\n?/, "")
  </code></pre>
