title: Multiple conditions in if statement shell script
body: <p>I would like to know whether it is possible to have more than two statements in an <code>if</code> statement when you are writing a shell script?</p>
  
  <pre><code>username1="BOSS1"
  username2="BOSS2"
  password1="1234"
  password2="4321"
  
  if(($username == $username1)) &amp;&amp; (($password == password1)) || 
    (($username == $username2)) &amp;&amp; (($password == password2)) ; then
  </code></pre>
  
  <p>This does NOT work. But is there a way to make it work?</p>
  
  <p>Thanks!</p>
