lsof 中的 DEVICE 字段代表什么？

以下是 lsof -i tcp:XXXXXX 的删节输出：

COMMAND PID  USER FD TYPE DEVICE
python3 9336 root 3u IPv4 3545328
python3 9336 root 5u IPv4 3545374

答案1

$ man 8 lsof | grep -A 10 '^\s\{7\}DEVICE'
   DEVICE     contains the device numbers, separated by commas, for a character special, block special, regular, directory or NFS file;

              or ``memory'' for a memory file system node under Tru64 UNIX;

              or the address of the private data area of a Solaris socket stream;

              or a kernel reference address that identifies the file (The kernel reference address may be used for FIFO's, for example.);

              or the base address or device name of a Linux AX.25 socket device.

              Usually only the lower thirty two bits of Tru64 UNIX kernel addresses are displayed.

或输入

man 8 lsof

您可以使用 Inside man 进行搜索/。比直接键入不带空格的正则表达式。在你的情况下^\s*DEVICE，你会跳到DEVICE.
