我运行此命令并得到了此结果,但无法理解结果我应该杀死哪个节点实例
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
以及 S+ Sl+ T, R + 是什么意思?

这些是进程状态代码 - 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
