title: Paths must precede expression Linux find
body: <p>I have the following command:</p>
  
  <pre><code>find -xtype f -iname '*NEN*' -o '*1990*'
  </code></pre>
  
  <p>I get the error "find: paths must precede expression: <em>1990</em>"
  Why is this? I have quoted the wildcard, so I don't see the error. How to fix this?</p>
  
  <p>Thanks!</p>
