See what process is using a file in Mac OS X
提问by JPC
I would like to be able to track a file and see which process is touching that file. Is that possible? I know that I can see the list of open processes in activity monitor but I think it's happening to quickly for me to see it. The reason for this is I'm using a framework and I think the system version of the framework is being used instead of the debug version and I'd like to see which process is touching it.
我希望能够跟踪文件并查看哪个进程正在访问该文件。那可能吗？我知道我可以在活动监视器中看到打开的进程列表，但我认为我很快就能看到它。这样做的原因是我正在使用一个框架，我认为正在使用该框架的系统版本而不是调试版本，我想看看哪个进程正在接触它。

lsofwill list open files, but it can be a bit awkward for momentary touches (eg, if the file isn't open when lsof runs, it doesn't show).
lsof将列出打开的文件，但对于暂时的触摸可能有点尴尬（例如，如果 lsof 运行时文件未打开，则不会显示）。
I think your best bet would be fernLightning's fseventer.app. It's "nagware", and allows you to watch (graphically) the fsevents API in real-time.
我认为你最好的选择是 fernLightning 的fseventer.app。它是“nagware”，允许您实时（以图形方式）观看 fsevents API。

That's simple: sudo fs_usage | grep [path_to_file]
这很简单： sudo fs_usage | grep [path_to_file]

But I spent 2 minutes Googling and found your answer here.
$ lsof | grep [whatever]
Where [whatever] is replaced with the filename you're looking for. With this, you can see which program is desperately holding onto your about-to-be-trashed file. Once you exit that program, your trash will empty.
$ lsof | grep [随便]
其中 [whatever] 替换为您要查找的文件名。有了这个，您可以看到哪个程序拼命保留您即将被删除的文件。退出该程序后，您的垃圾箱将清空。

The faster way is:
更快的方法是：
$ lsof [path_to_file]
This solution doesn't require the root password and gives you back the following, clear, result:
此解决方案不需要 root 密码，并为您提供以下清晰的结果：
