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:
< 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
