title: how to drop lines when streaming from a file using Haskell and the turtle library
body: <p>Let's say I want to stream from one file to another file but I want to skip the first n lines of the input file. How do I do this without first collapsing the whole first file using 'fold' ?</p>
  
  <pre><code>import Turtle
  main = output "/tmp/b.txt" (f (input "/tmp/a.txt"))
  </code></pre>
  
  <p>What should 'f' be here to accomplish this ?</p>
  
  <p>ps: I don't have enough reputation to create the 'haskell-turtle' tag.</p>
