  • Unfortunately in the AIX system that I'm uing top is unavailable and has topas. ps -eo pcpu,pid,args | sort -rk1 | head -6 does give the output, but the result doesn't match with the result of topas. Commented Oct 10, 2013 at 8:15
  • @debal Why must the result match topas? Commented Oct 10, 2013 at 8:16
  • both these commands tend to do the same thing, wouldn't it be surprising if the two results don't match? topas is giving a realtime view of the CPU usage, ps -eo pcpu,pid,args | sort -rk1 | head -6 is giving for a particular point of time, so at that instance it only makes sense if both these commands provide the same result. Which is not the case. Commented Oct 10, 2013 at 8:20
  • That's not exactly the contrast point -- ps gives you a weird process lifetime vs. CPU seconds which is not necessarily indicative of what's causing high CPU "recently". topas, like top, gives you the % over a much short reasonable that is intuitively usually what people want.
