how to keep laravel queue system running on server code example

Example 1: running queue on server

nohup php artisan queue:work --daemon &

nohup php artisan queue:work --daemon > /dev/null 2>&1 &

nohup php artisan queue:work --daemon > app/storage/logs/laravel.log &

Example 2: 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.
