从Python查找Linux中特定PID的命令 [英] Finding the command for a specific PID in Linux from Python

问题描述

我想知道是否有可能找出PID设置为的命令".当我说命令时，我的意思是当您在linux shell中运行命令"top"时在最后一栏中看到的内容.当我具有特定的PID时，我想以某种方式从Python获取此信息.

I'd like to know if it's possible to find out the "command" that a PID is set to. When I say command, I mean what you see in the last column when you run the command "top" in a linux shell. I'd like to get this information from Python somehow when I have a specific PID.

任何帮助都会很棒.谢谢.

Any help would be great. Thanks.

推荐答案

请不要在生产代码中使用/proc文件系统.相反，请使用定义明确的POSIX接口，例如glibc调用和标准的shell命令！确实需要使Linux世界更加标准化！

PLEASE, do not use /proc filesystem in production code. Instead, use well-defined POSIX interfaces, such as glibc calls and standard shell commands! Make the Linux world more standardized, it really needs to!

通过调用shell命令可以很好地实现

What you need is well achieved by invoking a shell command

ps -p <YOUR PID> -o cmd h

无需解析！

更不用说从python读取shell命令输出要比从/proc中的文件读取更多的工作.而且，这也使您的程序更易于移植！

Let alone that reading shell command output from python takes no more effort than reading from a file in /proc. And this makes your program more portable, either!
