title: bash shell script case statement for two variables
body: <p>I want to create a case statement including two expressions, my imagination is to look like this : </p>
  
  <pre><code>a=true
  b=false 
  
  case [ "$a" || "$b"]  in  #&lt;-- how can I do this with a case statement ?
  
  true)echo "a &amp; b are true" ;;
  false)echo "a or b are not true" ;;
  
  esac
  </code></pre>
  
  <p>Is it possible to do it with case instead of if ? </p>
  
  <p>Thanks </p>
