前言

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:

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.logT 6777 9654 tail -60f alert_pps.logT 6777 10724 top# kill -9 8635# ps -A -ostat,ppid,pid,cmd | grep -e "^[T]"T 6777 9654 tail -60f alert_pps.logT 6777 10724 top# kill -9 9654# kill -9 10724
