title: Why does my sequence result in "syntax error near unexpected token"?
body: <p>I have written this code to ping multiple IP addresses but it does not work. Can anyone please tell me what's wrong here? </p>
  
  <pre><code>#!/bin/bash
  for i in 'seq 1 20' do  
      ping -c 1 "10.88.209.$i";
  done
  </code></pre>
  
  <p>ps: the error it is showing is =>
  ./ping.sh: line 3: syntax error near unexpected token <code>ping'
  ./ping.sh: line 3:</code>    ping -c 1 "10.88.209.$i";'
  </p>
