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
D 无法中断的休眠状态(通常 IO 的进程);
R 正在运行可中在队列中可过行的;
S 处于休眠状态;
T 停止或被追踪;
W 进入内存交换(从内核2.6开始无效);
X 死掉的进程(从来没见过);
Z 僵尸进程;
< 优先级高的进程
N 优先级较低的进程
L 有些页被锁进内存;
s 进程的领导者(在它之下有子进程);
l 多进程的(使用 CLONE_THREAD, 类似 NPTL pthreads);
+ 位于后台的进程组;
