Get PID Number from “ps aux --sort -rss ”

Hi everyone
How can I just get the PID of the following command:

Code:
ps aux --sort -rss

Thanks

Regards

Did you consider ps' OUTPUT FORMAT CONTROL with the -o pid STANDARD FORMAT SPECIFIER? It doesn't bear with the u option, though.

So
Code:
ps aux

will give you every process (including those not in a terminal) in a user-readable output. As you are using --sort I assume you are using the GNU version of ps. Also you require to pull the PID of each process from this list so you don't need the user-friendly switch.

The following uses the SysV options to list all processes; sort them as you were in the original post; listing only the PID.
Code:
ps -e --sort -rss -opid=
