title: Finding highest value of variable
body: <p>So i am trying to find the highest value of the variable. For example o have this:</p>
  
  <pre><code>var1=14
  var2=15
  var3=16
  </code></pre>
  
  <p>I want to find the biggest value which is var 3 and save it somewhere. Is there a way to do that?</p>
  
  <p>Something like this:</p>
  
  <pre><code>tmp=`sort -n $var1 $var2 $var3  ` (this is an example)
  </code></pre>
