title: Bash run in background doesn't return to prompt
body: <p>Whenever I run a command in bash with "&amp;" at the end it doesn't return to prompt. Instead, it hangs even when the command is finished.</p>
  
  <p>Isn't running a process in the background supposed to return the prompt immediately so you can continue working without hanging till the command finishes.</p>
  
  <p>For example if I run "find" without "&amp;" it executes and returns the prompt. If I run it with same parameters and "&amp;" then it finishes and then hangs without doing anything.</p>
  
  <p>How to run a bash command correctly in the background ?</p>
