s + S1 + T R +在ps ax ps列表中的含义


37

我运行此命令并获得结果,但无法理解我应该杀死哪个节点实例的结果

 ps ax | grep node


23308 pts/3    S+     0:00 sudo node index.js
23310 pts/3    Sl+    0:00 node index.js
23568 pts/1    T      0:00 sudo node index.js
23824 pts/4    S+     0:00 sudo node index.js
23826 pts/4    Sl+    0:00 node index.js
24202 pts/5    R+     0:00 grep --color=auto node

S + Sl + T,R +是什么意思?

这些是过程状态代码-来自手册页

PROCESS STATE CODES
       Here are the different values that the s, stat and state output
       specifiers (header "STAT" or "S") will display to describe the state of
       a process.
       D    Uninterruptible sleep (usually IO)
       R    Running or runnable (on run queue)
       S    Interruptible sleep (waiting for an event to complete)
       T    Stopped, either by a job control signal or because it is being
            traced.
       W    paging (not valid since the 2.6.xx kernel)
       X    dead (should never be seen)
       Z    Defunct ("zombie") process, terminated but not reaped by its
            parent.

       For BSD formats and when the stat keyword is used, additional
       characters may be displayed:
       <    high-priority (not nice to other users)
       N    low-priority (nice to other users)
       L    has pages locked into memory (for real-time and custom IO)
       s    is a session leader
       l    is multi-threaded (using CLONE_THREAD, like NPTL pthreads do)
       +    is in the foreground process group

那么S +和S1 +之间的区别是什么?

@Antarus我相信Sl+不是S1+。意味着其处于可中断的睡眠,前台进程组和多线程。
