如何使用strace跟踪子进程? [英] How to track child process using strace?

问题描述

我使用strace简要地附加到进程.该过程创建了90个线程.当我找到有问题的线程时，我不得不繁琐地搜索父线程，然后是祖父母线程，等等，一直到根进程.

I used strace to attach to a process briefly. The process created 90 threads. When I found the offending thread, I had to tediously search for the parent thread, then the grandparent thread, and so on all the way to the root process.

是否有技巧或工具可以快速找出哪个线程创建了另一个线程?还是更好，打印诸如pstree之类的线程创建树?

Is there a trick or tool to quickly figure out which thread created another? Or better yet, print the tree of thread creations like pstree?

推荐答案

strace -f跟踪fork() ed的子进程.

strace -f to trace child process that's fork()ed.
