前言

在Linux系統下面，top命令可以查看查看stopped進程。但是不能查看stopped進程的詳細信息。那么如何查看stopped 進程，并且殺掉這些stopped進程呢？ps -e j | grep T

stopped進程的STAT狀態為T，一般而言,進程有下面這些狀態碼:

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

一般較常見的是5種狀態碼:

D 不可中斷 uninterruptible sleep (usually IO)

R 運行 runnable (on run queue)

S 中斷 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的進程信息。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
