這個過程 STAT 表示什麼？

如果您檢查STAT column上圖，您將看到Ss S S< SN and R+ 這表明什麼？Process states. 如果是，那意義'Ss S< SN and R+'何在？

這些確實是過程狀態。ps 指示的程序狀態為：

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.

附加字元是：

< 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 

您還可以通過查看手冊頁找到這一切ps，特別是該PROCESS STATE CODES部分。
