本文主要向大家介紹了Linux運維知識之Linux清除stopped程序,通過具體的内容向大家展現,希望對大家學習Linux運維知識有所幫助。
在Linux系統下面,top指令可以檢視檢視stopped程序。但是不能檢視stopped程序的詳細資訊。那麼如何檢視stopped 程序,并且殺掉這些stopped程序呢?
ps -e j | grep T
stopped程序的STAT狀态為T,一般而言,程序有下面這些狀态碼:
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
rs 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種狀态碼:
D 不可中斷 uninterruptible sleep (usually IO)
R 運作 runnable (on run queue)
S 中斷 sleeping
T 停止 traced or stopped
Z 僵死 a defunct (”zombie”) process
是以,可以用下面指令ps -A -ostat,ppid,pid,cmd | grep -e ‘^[T]’ 檢視stopped的程序資訊。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
