laravel queue:work not workingf code example

Example: 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
