   Hey there!

   I am developer of nginx-champuru.
   http://wordpress.org/extend/plugins/nginx-champuru/

   I want to implement auto flush nginx cache on this plugin.

   public function flush_caches()
   {
       if (defined("NGINX_DELETE_CACHES") && NGINX_DELETE_CACHES) {
           if (defined("NGINX_CACHE_DIR") && NGINX_CACHE_DIR) {
               $this->cache_dir = NGINX_CACHE_DIR;
           }
           $cmd = sprintf(
               'grep -lr %s %s | xargs rm -f >/dev/null &',
               escapeshellarg(home_url()),
               escapeshellarg($this->cache_dir)
   
           );
           exec($cmd);
       }
   }

   This function will exec on the hooks below.
   (publish_future_post hook will work by ajax.)

   • save_post
   • publish_future_post
   • comment_post

   I want to implement this function safely.
   Please advice me!

   If there are some mistakes in English, I'd like to apologize.
