我运行此命令并得到结果,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
什么S Sl T,R意味着什么？

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
