   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.
