如何查杀stopped进程

在Linux系统下面，top命令可以查看查看stopped进程。但是不能查看stopped进程的详细信息。那么如何查看stopped 进程，并且杀掉这些stopped进程呢？

ps?-e?j?|?grep?T?

stopped进程的STAT状态为T，一般而言,进程有下面这些状态码：

D????uninterruptible?sleep?(usually?IO)
I????Idle?kernel?thread
R????running?or?runnable?(on?run?queue)
S????interruptible?sleep?(waiting?for?an?event?to?complete)
T????stopped?by?job?control?signal
t????stopped?by?debugger?during?the?tracing
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

<????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

一般较常见的是5种状态码：

 	D 不可中断 uninterruptible sleep (usually IO)
        R 运行 runnable (on run queue)
 	S 中断 sleeping
 	T 停止 traced or stopped
 	Z 僵死 a defunct (”zombie”) process

所以，可以用下面命令ps -A -ostat,ppid,pid,cmd | grep -e ‘^[T]‘ 查看stopped的进程信息，进而使用kill命令将进程完全杀死。如下所示：

#??ps?-A?-ostat,ppid,pid,cmd?|?grep?-e?'^[T]'

T?????6777??8635?more?alert_pps.log
T?????6777??9654?tail?-60f?alert_pps.log
T?????6777?10724?top
#?kill?-9?8635
#??ps?-A?-ostat,ppid,pid,cmd?|?grep?-e?'^[T]'
T?????6777??9654?tail?-60f?alert_pps.log
T?????6777?10724?top
#?kill?-9?9654
#?kill?-9?10724
