linux - 如何杀死不存在的程序进程

标签 linux kill ps

前几天，我在我的ubuntu 16.04上安装了shellinabox，因为我不再使用它了，所以我通过sudo apt-get remove shellinabox卸载了它。卸载成功后，查看进程，发现shellinabox进程还在，如果杀掉这个进程，过几秒又会显示。

最佳答案

感谢@Amadan和@pitseeker，我检查了父进程的pstree，发现奇怪的进程可能是docker容器中的shellinabox进程，因为我也运行了shellinabox docker容器。

ldh@ldh55:~$ pstree -p 5675
