杀死(1)
$ man 1 kill
...
If sig is 0, then no signal is sent, but error checking is still performed.
...
杀死(2)
$ man 2 kill
...
If sig is 0, then no signal is sent, but error checking is still performed;
this can be used to check for the existence of a process ID or process
group ID.
...
所以信号 0 实际上不会向您的进程的 PID 发送任何内容，但实际上会检查您是否有权这样做。
虽然 kill -9 - 实际上发送 SIGKILL 到 PID
