title: QNX shell loop sequence
body: <p>Both following examples work in modern Bash but don't work in different sh shells (like QNX shell).</p>
  
  <pre><code>$ for i in {1..3}; do echo $i; done
  1
  2
  3
  
  $ for i in $(seq 1 3); do echo $i; done
  1
  2
  3
  </code></pre>
  
  <p>Is there any alternative method to produce same sequence in QNX shell?</p>
