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.
