我运行这个命令,并得到了这个结果,但不能理解哪个节点实例应该杀死的结果
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
以及什么S + S1 + T,R +意味着什么?
这些是来自手册页的进程状态代码
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
