如何显示 bash 会话的当前进程树? [英] How to display the current process tree of a bash session?

问题描述

我想创建一个 bash 别名，为我提供从我正在使用的当前 bash 会话到 init 的进程树.

I would like to create a bash alias that gives me the process tree from the current bash session I am using, up to init.

用例是知道我是否使用过bash 或vi 的:shell 命令.

The use case is to know whether I have used bash or vi's :shell command.

我用的是MacOS X，听说过pstree，但好像只显示子进程，不显示init和当前进程的关系.

I am using MacOS X. I have heard about pstree, but it seems to only show children, not the relationship between init and the current process.

推荐答案

我相信通过一些谷歌搜索，您可以找到如何获取和下载 Mac 版 pstree.但是，您可以使用ps 和ppid 来制作穷人版.

I am sure with a a bit of google search, you can find how to get and download pstree for the Mac. However, you can do a poor man's version, using ps and ppid.

例如

ps -eo ppid,pid,cmd | awk '{p[$1]=p[$1]","$3}END{ for(i in p) print i, p[i]}'
