How to display list of processes sorted in reverse order for a bash, tsch, ksh shell in Unix
提问by Masterminder
Was wondering if someone could help me with this... I want to display a list of running processes sorted in reverse order. The reverse order is to be based on process identification value - PID.
想知道是否有人可以帮助我...我想显示按相反顺序排序的正在运行的进程列表。相反的顺序是基于过程识别值 - PID。
I was also wondering does it matter for the processes to be displayed in a certain shell? do I have to include something specific in the line of code or merely just change shells. I want to do this for both tsch and bash.
我还想知道在某个 shell 中显示进程是否重要？我是否必须在代码行中包含特定的内容，或者只是更改 shell。我想为 tsch 和 bash 执行此操作。
I have looked up the commands but I am not sure how to bring it together. See below:
我已经查找了命令，但我不确定如何将它们组合在一起。见下文：
ps = is the command that shows information about processes running in memory
-p = by process ID
r = running processes
sorting method?
Not sure how to bring it together.
不知道如何把它放在一起。
Thanks for the help
谢谢您的帮助

This will do it:
这将做到：
ps aux | sort -k2 -rn
The pscommand varies depending on OS. I can confirm the above will work in Linux and FreeBSD.
该ps命令取决于操作系统。我可以确认以上在 Linux 和 FreeBSD 中都有效。

ps has it's own sort on linux, This is how I use it:
ps 在 linux 上有它自己的排序，这就是我使用它的方式：
ps -eo pid,user,rss,vsz,pmem,comm,lstart --sort rss
In your case
在你的情况下
ps aux --sort pid
回答by BigBear
In bash the following command will do it:
在 bash 中，以下命令将执行此操作：
~$ ps aux --sort -pid | less
Normal (descending) order is achieved by specifying --sort pidor --sort +pid. The latter doesn't make much sense though.
正常（降序）顺序是通过指定--sort pid或来实现的--sort +pid。不过后者意义不大。
