在lsof中设备场代表什么？

Question

以下是lsof -i tcp:XXXXXX的简短输出：

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

Answer 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.

或类型

man 8 lsof

内部人，你可以搜索与/。而不是直接输入没有空格的正则表达式。在您的例子中，^\s*DEVICE和您将跳到DEVICE。
