title: List only certain files in a directory matching the word BOZO and ending with either '123' or '456'
body: <p>I'm trying to figure out how to get a list of file names for a file named BOZO but ending with ONLY 123 OR 456.</p>
  
  <p>Files are:</p>
  
  <p>BOZO12389,<br>
  BOZOand3<br>
  BOZOand456<br>
  BOZOand5<br>
  BOZOhello123</p>
  
  <p>So the command should only display 'BOZOhello123' and 'BOZOand456'</p>
  
  <p>I can't figure it out. I've tried all forms of LS and GREP that I can think of. The funny thing is, we tried to do it in class for about 10mins and no one could get it (including the instructor). </p>
