title: Is it safe to run cat command on a .zip file?
body: <p>In bash, when I run <code>cat</code> on a <code>.zip</code> file, it outputs a bunch of symbols that scroll up the screen quickly. It also makes some beeping noises. This is both a little scary and awesome.</p>
  
  <p>Is it safe for me to keep doing this? I kind of want to have this as a trick up my sleeve, so to speak. I want to <em>wow</em> my friends, family and future employers; and I know this trick is sure to impress.</p>
  
  <p>Anyone know if there are any harmful effects from doing this?</p>
