title: Unix cat command problems
body: <p>I started a command line online course last night. I was playing around with some basic commands and for some reason, every time I use cat mydoc.txt or mydoc.docx, it only outputs question marks and other random symbols to the terminal. I searched this site and google and can't find an exact solution to this specific problem. I came across a couple of sites that said maybe try changing the file permission but that didn't seem to affect the output.</p>
  
  <p>Any insight is appreciated! </p>
