title: Read Certain Lines from File
body: <p>Hi just getting into Ruby, and I am trying to learn some basic file reading commands, and I haven't found any solid sources yet.</p>
  
  <p>I am trying to go through certain lines from that file, til the end of the file.</p>
  
  <p>So in the file where it says FILE_SOURCES I want to read all the sources til end of file, and place them in a file.</p>
  
  <p>I found printing the whole file, and replacing words in the file, but I just want to read certain parts in the file.</p>
