bash ps; remove the header, sort and reinsert

Hi,
I'm ssh'ing into a server using ruby and sending a one-liner to retrieve the output of the 'ps aux' command. So far, this is what I have:
ps aux | sort -r -n -k3 | sed -e '1s/^/this is first\n/' | head -n10

With this I can insert a line at position 1, but I would rather extract the header before the sort and reinsert it before the pipe to head.

Any help is appreciated.

Hi..

If you remove the -n option from sort, the header appears first. Is thiat not what you want?

Exactly! I had a feeling that I was missing something obvious. Thanks a bunch.

Why does removing the -n option do that? Does the -n option change all values in a column to a number or something?
