body: <p>This question is different from <a href="https://stackoverflow.com/questions/7773738/execute-an-array-of-string-describing-shell-command">Execute an array of string describing shell command</a>.</p>
  <p>For example, we have an array</p>
  <pre><code>myarr=( echo hello you )
  </code></pre>
  <p>How to execute it as one command, i.e. run <code>echo hello you</code> itself?</p>
