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？

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
