First we create the command with

php artisan make:command AppName

Then we replace the content created in the file app/Console/Commands/AppName.php with the content of the gist.

and then use it in the usual way, changing Luewell for the name of your application.

php artisan app:name Luewell

Thank you! Worked as well. 🎉 I don't know why Laravel removed this 😞

Thank you very much! It's work well for me.

well done ! @isluewell work nicely

Thank you!!

Thank You

Thank you, its work well

It works buy when I try to make migrations, I receive the next notification: Class 'App\Providers\RouteServiceProvider' not found. In fortify.php line 64: ¿Any idea how to solve it?

Me fue muy útil el contenido de esta página. Logré mi objetivo: cambiar el nombre de mi aplicación. Muchas gracias.

That's is worked. Thank you.

thanks! 🌻

Very useful for a quick change, thank you!
