title: POSIX sh syntax for for-loops [SC2039]
body: <p>The following command works well on my shell :</p>
  
  <pre><code>for ((j=0; j&lt;=24; j++))
  do &gt; $j.json
  done
  </code></pre>
  
  <p>but having the following notification :</p>
  
  <blockquote>
    <p>SC2039 In POSIX sh, arithmetic for loops are undefined.</p>
  </blockquote>
  
  <p>I was wondering what would be the equivalent in POSIX in order not to have interpeting issues on other systems.</p>
