1. Dolphin will first start a sudo root process
2. When kill, kill all child processes, the sudo process will also end
3. For this piece, why remove the first pid, because the first pid is a root-level process
```java
pidList = pidList.subList(1, pidList.size());
```
When using sudo -u tenant kill -9 pids, it will report insufficient permissions. If this is changed to sudo kill -9 pids, there is no need to remove the first pid above.
