title: Multithreading in Bash
body: <p>I would like to introduce multithreading feature in my shell script.</p>
  
  <p>I have a script which calls the function <code>read_cfg()</code> with different arguments.
  Each of these function calls are independent.</p>
  
  <p>Would it be possible to instantiate these function calls (not scripts) parallelly.
  Please let me how can we achieve that.. ?</p>
