Wow, writing Artisan Commands just become even easier. And plugging it into Scheduler makes for a great combination.

For example we need to clean out a folder every so many minutes. The example below I also for fun play around with progress and table output.

Note too protected $signature = 'approve:cleanuploads {--minutes=10}'; simplifies the argument and options features.

<php namespace App\Console\Commands; use Carbon\Carbon; use Illuminate\Console\Command; use Illuminate\Support\Facades\File; class CleanUploadsCommands extends Command { protected $rootPath = 'public/storage'; protected $maxMinutes = 10; protected $deleted = []; protected $signature = 'approve:cleanuploads {--minutes=10}'; protected $description = 'Clean all the uploads in the storage folder for security reasons'; protected $pdfFiles = []; protected $files = []; public function __construct() { parent::__construct(); } public function handle() { $this->maxMinutes = $this->option('minutes'); $this->anyPdfFilesHere(); $this->deletePdfFiles(); $this->outputResults(); } protected function anyPdfFilesHere() { $this->files = File::allFiles(base_path($this->rootPath)); foreach($this->files as $file) { if (File::mimeType($file) == 'application/pdf') { $this->pdfFiles[] = $file; } } } private function deletePdfFiles() { if(count($this->pdfFiles) > 0) { $this->output->progressStart(count($this->pdfFiles)); foreach($this->pdfFiles as $file) { $modified = File::lastModified($file); $minutes = Carbon::createFromTimestamp($modified)->diffInMinutes(); if($minutes > $this->maxMinutes) { $this->setDeleted(['filename' => $file]); File::delete($file); $this->output->progressAdvance(); } } } } private function outputResults() { if(count($this->deleted) > 0) { $this->output->progressFinish(); $headers = ['File Name and Path']; $this->table($headers, $this->getDeleted()); } else { $this->comment(sprintf("No files older than %d minutes", $this->maxMinutes)); } } public function getDeleted() { return $this->deleted; } public function setDeleted($deleted) { $this->deleted[] = $deleted; } }

Then in the Kernel.php I enter

<?php namespace Approve\Console; use Illuminate\Console\Scheduling\Schedule; use Illuminate\Foundation\Console\Kernel as ConsoleKernel; class Kernel extends ConsoleKernel { /** * The Artisan commands provided by your application. * * @var array */ protected $commands = [ 'App\Console\Commands\CleanUploadsCommands' ]; /** * Define the application's command schedule. * * @param \Illuminate\Console\Scheduling\Schedule $schedule * @return void */ protected function schedule(Schedule $schedule) { $schedule->command('approve:cleanuploads --minutes=10') ->everyMinute(); } }

And that is it.

One big thing about Commands is the power of Asynchronous processing that libraries like Symfony Process gives us the ability to run numerous commands at once!
