Linux：程序的CPU和内存使用情况

Question

I have a bash script that calls different c++ programs (some of them are multithread). I want to know what is the CPU and memory usage (maximum or average) during the execution of that script. There is a special tool for that?

Thanks.

Answer 1

除非要深入研究/proc/<pid>/... （其中<pid>是已启动程序的进程ID），否则可以使用ps 。

Answer 2

如果您知道“程序”的进程名称：

ps -C "processName" -o %cpu,%mem
