How do I remove old artisan command from Kernel in Laravel 5

Question

I have created some Command files into my Laravel Application. Laravel version is 5.2. I set command like: get:email in the Command file. Also call the Command file into Kernel.php. After that I can see the artisan command list by typing the command php artisan list. as like as below:

//output
get:email

And I changed the command title get:email to get-bq:email. When I run the command php artisan get-bq:email -- its working nicely. Also I can see the list by typing the command php artisan list::

//output
get-bq:email

Issue / Problem: Both commands are working. But I won't to work with both of them. I have done the following things:

1. modified command file as well as command
2. run composer dump-autoload -o
3. run composer update
4. remove vendor and storage folder then run composer update again.

Still the old command is working into my system.

What I want: How May I remove my old commands from my Laravel(5.2) application?

Answer 1

Run these commands:

php artisan cache:clear
php artisan config:clear

These commands will clear app cache and config cache and recreate it.

Answer 2

I've had the same problem recently.

Repoeatedly tried

php artisan cache:clear
php artisan config:clear

and the cached Kernal command wouldn't clear.

In desperation i killed the queue worker terminal and restarted the queue with the command

php artisan queue:work

The issue stopped.
