title: Are linux crons asynchronous or synchronous?
body: <p>I am new to CRONs. I have a doubt whether crontab command schedules a cron <code>asynchronously</code> or <code>synchronously</code>.?</p>
  
  <p>What I know and have observed is, the crontab creates a asynchronous process. Irrespective of the last execution, the new <code>cron</code> runs. That is, if I have scheduled a cron task every 2 minutes, then even if the previous execution is not over, a new thread will re-run the file.</p>
  
  <p>Am I correct.?</p>
