title: What is the gt for here? "if [ $VARIABLE -gt 0 ]; then"
body: <p>What does the <code>-gt</code> mean here:</p>
  
  <p><code>if [ $CATEGORIZE -gt 0 ]; then</code></p>
  
  <p>This is part of a bash script I'm working with.</p>
  
  <p>Also, where can I find a list of "flags" that go in there so I can have for reference in the future?</p>
