Linux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

       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

 

 

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。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
