There’s only 3 steps required to setting up new Artisan command.

1. Step 1 – Create a new console file

php artisan make:console CommandName

1. Step 2 – Open up app/Console/Commands/CommandName.php and update the signature and the description property.

     /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'env:db';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Configure database settings';

1. Step 3 – Register your new Artisan command in app/Console/Kernel.php

    /**
     * The Artisan commands provided by your application.
     *
     * @var array
     */
    protected $commands = [
        // CommandsInspire::class,
        CommandsDatabaseEnvironment::class
    ];

Now you’re ready with your new artisan command. Check your command with php artisan. It should have something like this one.

Here the a sample code.
