在OSX 10.9上Pstack一个进程 [英] Pstack a process on OSX 10.9

问题描述

在linux上，为了在给定的时间查看进程堆栈，我们通常使用

On linux in order to view the process stack at a given time we generally use

pstack< >

pstack <pid>

我想知道osx中的等效功能是什么.

I am wondering what is the equivalent of the same in osx.

谢谢

推荐答案

sudo /usr/libexec/stackshot -i -u -p <pid>

这会将有关进程的所有线程的堆栈跟踪附加到文件/Library/Logs/stackshot-syms.log中.考虑在调用stackshot之前删除文件stackshot-syms.log.另请:stackshot(1)

This appends a stack trace of all threads of the process in question to the file /Library/Logs/stackshot-syms.log . Consider to remove the file stackshot-syms.log before calling stackshot. See: stackshot(1)

注意:OS X 10.11 EL Capitan不再包含stackshot. 改用lldb调试器:

Note: stackshot is no longer included with OS X 10.11 EL Capitan. Use the lldb debugger instead:

echo "thread backtrace all" | lldb -p <pid>

lldb是命令行开发人员工具的一部分.如果您的计算机上没有lldb，则弹出窗口将帮助您安装XCode.

lldb is part of the command line developer tools. If you don't have lldb on your machine, a popup will help with installing XCode.
