Sorting down processes by memory usage

问题

I am able to see the list of all the processes and the memory via

ps aux 

and going through the VSZ and RSS column data.

Is there a way to sort down the output of this command by the descending order on RSS value ?.

PS : This is a newbie question as I am very much new to Unix/Linux. ubuntu

回答1:

RSS is the 6th column, so you can do it as follows:

ps aux | sort -k6,6 -rn

• sort based on column 6 only (the comma on 6,6 makes it, thanks twalberg), numerically and reverse (the biggest number first).
