title: Search for files in a folder
body: <p>I'm trying parse a lot of text files using Julia, and I want to loop across an array of file names instead of typing out a function call to read each of them individually. So far I have been unable to find a way to search a folder for files matching a pattern.</p>
  
  <p>Is there a base library Julia function that will return all file names in a given folder, matching a given string pattern?</p>
  
  <p>The equivalent function in R would be <code>list.files()</code>, if that helps communicate what I want.</p>
