Artisan command for clearing all session data in Laravel

What is the artisan command for clearing all session data in Laravel, I'm looking for something like:

$ php artisan session:clear

But apparently, it does not exist. How would I clear it from the command line?

I tried using

$ php artisan tinker  
...
\Session::flush();

But it flushes the session of only one user, I want to flush all sessions for all users. How can I do it?

I tried this:

artisan cache:clear

But it does not clear the session, again.

UPDATE: This question seems to be asked quite often and many people are still actively commenting on it.

In practice, it is a horrible idea to flush sessions using the

php artisan key:generate

It may wreak all kinds of havoc. The best way to do it is to clear whichever system you are using.

The Lazy Programmers guide to flushing all sessions:

php artisan key:generate

Will make all sessions invalid because a new application key is specified

The not so Lazy approach

php artisan make:command FlushSessions

and then insert

<?php

namespace App\Console\Commands;

use Illuminate\Console\Command;
use DB;

class flushSessions extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'session:flush';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Flush all user sessions';

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        DB::table('sessions')->truncate();
    }
}

and then

php artisan session:flush
