title: Parallel processing or threading in Shell scripting
body: <p>I am writing a script in shell in which a command is running and taking 2 min. everytime. Also, there is nothing we can do with this. But if i want to run this command 100 times in script then total time would be 200min. and this will create a big issue. Nobody want to wait for 200min. What i want is to run all 100 commands parallely so that output will come in 2min or may be some more time but dont take 200min.</p>
  
  <p>it will be appreciated, if any body can help me on this in any way. </p>
