正如你向我保证的那样，帖子标题是帖子“重复”状态的准确指示器，一点SQL和wp_delete_post() 可以做到：

$sql = "SELECT ID
  FROM {$wpdb->posts} 
  WHERE post_title REGEXP \'^.*-[[:digit:]]*$\'
  AND post_type = \'page\'";
$del = $wpdb->get_col($sql);
foreach ($del as $d) {
  wp_delete_post($d);
}

wp_delete_post($d,true);

根据以下评论：

我根据位置创建了页面，我刚刚意识到我有一些页面，比如Berwick on Tweed和Berwick on Tweed，我会Ideally like to delete the pages with the - in the title...

我忍不住认为这是一件非常危险的事情，但SQL很简单：

$sql = "SELECT ID
  FROM {$wpdb->posts} 
  WHERE post_title LIKE \'%-%\'
  AND post_type = \'page\'";
