列出使用 /mountpoint 挂载的挂载上的文件的进程。 对于查找哪些进程正在使用已安装的 USB 记忆棒或 CD/DVD 特别有用。
lsof +f -- /mountpoint
lists the processes using files on the mount mounted at /mountpoint. Particularly useful for finding which process(es) are using a mounted USB stick or CD/DVD.
lsof -i 将提供开放网络套接字的列表。 -n 选项将阻止 DNS 查找，这在网络连接速度慢或不可靠时非常有用。
lsof -i will provide a list of open network sockets. The -n option will prevent DNS lookups, which is useful when your network connection is slow or unreliable.

将递归显示目录中打开的所有文件。 +d 仅代表顶层。
当您的 IO 等待百分比很高（与特定 FS 上的使用相关）并且想要查看哪些进程正在消耗您的 io 时，这非常有用。
Will display recursively all the files opened in a directory. +d for just the top-level.
This is useful when you have high wait% for IO, correlated to use on a particular FS and want to see which processes are chewing up your io.
查看正在运行的应用程序或守护程序打开了哪些文件：
其中 pid 是应用程序或守护程序的进程 ID。
See what files a running application or daemon has open:
Where pid is the process ID of the application or daemon.
