how queue and jobs in laravel code example

Example 1: 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.

Example 2: laravel queue:work not working

Execute Laravel queues by queue names on coomand line interface-> 
// I was using running command
  'php artisan queue:work'    
// which was not running my queued jobs in jobs table. 
// Then i relaized, it was only working for jobs with queue column value = 'default'
// and  i had given names like sendemail, inboxemail etc. 
  
// So when i changed this other value to  'default'  in queue column in jobs table,
// this job ran instantly as i have opended cli and  php artisan queue:work 
// command was active.  
  
//So if you want to run only a specific queue by queue name, run command ->   
  php artisan queue:listen --queue=sendemail 
//    or 
  php artisan queue:listen --queue=inboxemail
