小编给大家分享一下Linux中pstack命令怎么用，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
pstack命令 可显示每个进程的栈跟踪。
显示每个进程的栈跟踪
pstack 命令必须由相应进程的属主或 root 运行。可以使用 pstack 来确定进程挂起的位置。此命令允许使用的唯一选项是要检查的进程的 PID。
命令软件包下载地址：https://packages.debian.org/sid/pstack
pstree以树结构显示进程
pstree -p work | grep ad sshd(22669)---bash(22670)---ad_preprocess(4551)-+-{ad_preprocess}(4552) |-{ad_preprocess}(4553) |-{ad_preprocess}(4554) |-{ad_preprocess}(4555) |-{ad_preprocess}(4556) `-{ad_preprocess}(4557)work为工作用户，-p为显示进程识别码，ad_preprocess共启动了6个子线程，加上主线程共7个线程。
