请问ps中如果文件出现[程序名]中的方括号是啥意思

zhangych

目前编写的程序用ps 命令查看时会出现带方括号的情况,系统整体运行有问题,请问这个程序在什么状态啊.

With the -o flag, the ps command examines memory or the paging area and determines what the command name and parameters were when the process was created. If the ps command cannot find this information, the command name stored in the kernel is displayed in square brackets.

a.a

比如说像[defunct]之类的？
