这篇文章将为大家详细讲解有关Linux查看进程栈信息的示例，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

示例：

Linux查看进程栈信息的示例

先准备一段程序，为了简单起见这里使用python来写，其中创建了两个线程来执行各自的任务。

importthreading
importtime
deftest1():
while(True):
time.sleep(1)
print'test1'

deftest2():
while(True):
time.sleep(1)
print'test2'
t1=threading.Thread(target=test1,args=())
t2=threading.Thread(target=test2,args=())
t1.start()
t2.start()
time.sleep(12345)

然后运行这个程序

$pythontest.py

先使用 “pstree -apl ” 查看进程结构

$pstree-apl26855
python,26855test.py
|-{python},26858
|-{python},26859

然后使用 “ps -Lf ” 查看线程信息

$ps-Lf26855
UIDPIDPPIDLWPCNLWPSTIMETTYSTATTIMECMD
jhadmin2685525902268550315:15pts/5Sl+0:00pythontest.py
jhadmin2685525902268580315:15pts/5Sl+0:00pythontest.py
jhadmin2685525902268590315:15pts/5Sl+0:00pythontest.py

最后，可以使用 “pstack ” 查看线程的详细信息，如下：

$pstack26855

这里多说一句，如果要看java程序的栈信息，可以使用 “kill -3 ” 来查看，比如：
