推荐答案

如果您使用的是Linux，但可移植性更高的解决方案，则可以使用Ipor的方式(/proc/< pid>/status )适用于大多数Unix/Unix之类的操作系统的操作是使用Barmar在注释中已经建议的标准命令:

You might use Ipor's way (/proc/<pid>/status) if you are using Linux but a more portable solution that should work with most Unix/Unix likes OSes would be to use a standard command as Barmar already suggested in a comment:

ps -o s= -p <pid>

这将显示已暂停进程的 T (也由于调试而停止).

This will show T for a suspended process (also if stopped because being debugged).
