查找运行进程的处理器ID(通过类似于顶部的命令/界面) [英] Finding processor id in which process is running [through command/interface similar to top]

问题描述

有什么办法可以让CPU获得进程正在运行的CPU?

Is there any way i can get the CPU which CPU the process is running?

推荐答案

您可以使用/proc/[id]/stat文件并读取第39个值(用空格分隔).这说明[pid]的进程当前在哪个CPU ID上运行:

You can use /proc/[id]/stat file and read the 39th value (seperated by spaces). This tells which cpu id the process of [pid] is currently running on:

cat /proc/[id]/stat | awk '{print $39}'

有关更多信息: man proc .
