title: Semicolons superfluous at the end of a line in shell scripts?
body: <p>I have a shell script which contains the following:</p>
  
  <pre><code>case $1 in
      0 )
      echo $1 = 0;
      OUTPUT=3;;
      1 )
      echo $1 = 1;
      OUTPUT=4;;
      2 )
      echo $1 = 2;
      OUTPUT=4;;
  esac
  
  HID=$2;
  BUNCH=16;
  LR=.008;
  </code></pre>
  
  <p>Are <em>semicolons</em> completely superfluous in the snippet above? And is there any reason for some people using double semicolons?</p>
  
  <p>It appears semicolons are only a separator, something you would use instead of a new line.</p>
