Quick and dirty script to keep my Screenshot folder clean and properly named.

shots.php

#!/usr/bin/php
<?php

date_default_timezone_set("America/Chicago");
$who = trim(`whoami`);
$base = "/Users/{$who}/Dropbox/Screenshots/";
$files = glob("{$base}*.png");

foreach($files as $file)
{
	$original = $file;
	if(preg_match("/Screenshot (.*)\.png/",$file,$match))
	{
		$dt = str_replace(" at "," ",$match[1]);
		if(strpos($dt," (2)"))
		{
			$dt = str_replace(" (2)","",$dt);
			$timestamp = strtotime($dt) + 1;
		}
		else
			$timestamp = strtotime($dt);

		$datetime = date("Y-m-d H.i.s",$timestamp);
		if($datetime)
		{
			// crushing PNG with PNGquant
			exec("pngquant " . escapeshellarg($original) . " --output " . escapeshellarg($base.$datetime.".png"), $output, $code);
			if($code == 0)
				unlink($original);
			else
				echo "Something went wrong! Error Code: $code\n";
		}
	}
}
