title: How to return a collection of files from a given directory in Elixir?
body: <p>In Ruby, I can use </p>
  
  <pre><code>target_files = Dir["/some/dir/path/*.rb"]
  #=&gt; ["/some/dir/path/foo.rb", "/some/dir/path/bar.rb", "/some/dir/path/baz.rb"]
  </code></pre>
  
  <p>which will return an array of all of the matching files in a directory. How can I do something similar in Elixir?</p>
