What Others Think

Hmm... That's useful (and you can make it a bit tidier). grep, grep, awk My guess is that you're grep'ing twice to avoid grep showing up in the results. grep "XYZ" | grep -v grep The trick is: grep "XY[Z]" The [Z] matches Z but the ps listing contains '[' 'Z' ']' Next, awk can do that for you, so you don't need grep at all. Finally, the semicolon after the sum clause isn't necessary. ps axo pcpu,args | awk '/[p]hp.*pool/{sums[$4] += $1} END {for (pool in sums) {print sums[pool], pool}}' | sort -rn | column -t
