laravel 8 queue banstalk full example

Example: how to automatically run queue in laravel

for queues with no queue name i.e. queue name = default
	php artisan queue:work 
  		or
	php artisan queue:listen
      
for jobs with a queue name. Let's assume i have a queue with name = sendemail

	php artisan queue:listen --queue=sendemail   
    
note: 
queue:work will only work for jobs entries currently in jobs table in database and stop.
queue:listen  will go on processing queues continously, both for current and new entries.
