ps ax psリストでのs + S1 + T R +の意味

私はこのコマンドを実行して結果を取得しましたが、どのノードインスタンスを強制終了するか結果を理解できません

 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

そして、S + Sl + T、R +はどういう意味ですか？

これらは man page からのプロセスSTATEコードです。

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
