title: How can I tell whether I installed Homebrew correctly?
body: <p>A while ago, I installed Homebrew on my Mac and I'm worried I did it incorrectly and it's causing Brew not to work correctly. Is there some kind of command I can run from terminal to check if everything is working correctly?</p>
  <p>There are two reasons I'm worried that it's not set up correctly:</p>
  <ol>
  <li>I'm watching <a href="https://www.youtube.com/watch?v=SELYgZvAZbU" rel="nofollow noreferrer">this tutorial</a> in which he runs the command <code>brew search</code> and it gives him a list of packages he can install. But when I run the command I get the error message <code>This command requires at least 1 text or regex argument.</code> Is this normal?</li>
  <li>When I run brew commands, it takes much longer than when I run other commands from terminal (maybe 3 seconds). Is this normal?</li>
  </ol>
