我正在编写一个脚本来监视任何给定进程的 CPU 和 MEM.为此，我需要将要监视的进程的名称作为命令行参数发送.例如.

I am writing a script to monitor the CPU and MEM of any given process. For that i need to send in the name of the process to be monitored as a commandline argument. For example.

./monitorscript <pname>

我需要在脚本中获取进程的 pid 以便我可以在里面使用 ps -p .

如何根据进程名称获取进程的 pid?
