推荐答案

从简单的学习 FSEvents API 我想说，你想要的是不可能的。我可能会误解，但我从来没有使用FSEvent。 这个问题的提问者已经通过用<$分别监视新文件解决了这个问题c $ c> lsof 。

From simply studying the FSEvents API I would say that what you want is not possible. I could be mistaken, though, I have never used FSEvents myself. The asker of this question has solved the problem by separately monitoring the new file with lsof.
