title: how to parse a config file (*.conf) in shell script?
body: <p>I am new to shell script. I have a file <code>app.conf</code> as :</p>
  
  <pre><code>[MySql]
  user = root
  password = root123
  domain = localhost
  database = db_name
  port = 3306
  
  [Logs]
  level = logging.DEBUG
  
  [Server]
  port = 8080
  </code></pre>
  
  <p>I want to parse this file in shell script and want to extract mysql credentials from the same. How can I achieve that?</p>
