<?php

declare(strict_types = 1);

const PATTERN = '/(-m\d-[a-zA-Z]*-[0-9][0-9])/';

if (empty($argv[1])) {
    throw new Exception('Usage: php rename.php <directory_path>');
}

$path = str_replace('//', '/', $argv[1] . '/');

$newFiles = [];
foreach (scandir($path) as $fileName) {
    if ('.' === $fileName || '..' === $fileName) {
        continue;
    }
    preg_match(PATTERN, $fileName, $matches);
    $matched = reset($matches);
    if (is_bool($matched)) {
        throw new Exception(sprintf('File name "%s" can not be matched', $fileName));
    }

    $newName = substr($matched, 1, strlen($matched)) . '_' . preg_replace(PATTERN, '', $fileName);
    rename($path.$fileName, $path.$newName);
