summary field

Do you mean you want to have %CPU and %MEM being summed up and displayed as last line?

Maybe, this is what you are looking for:

# ps -efo user,pcpu,pmem,comm | grep oracle | nawk 'BEGIN {s1=0;s2=0}
  {print $2,$3; s1=s1+$2; s2=s2+$3}
END {printf("Totals: %d %d\n",s1,s2) }'

Sorry: Replace "oracle" with "root" -- that's the way I developed and tested it ...

excelent justunix!  but please make it searchable both by user and comm, right now comm cannot summarise . Obviously it can be script then with one argument comm or user.
ps -efo user,pcpu,pmem,comm | grep ping | nawk 'BEGIN {s1=0;s2=0}
  {print $2,$3,$4; s1=s1+$2; s2=s2+$3}
END {printf("Totals: %d %d\n",s1,s2) }'

What do you mean by "searchable" ?

Can you post some output -- how you would like to have the result?

Ok, please see grep there, I would like to put user or comm after grep. so it makes it more universal.
Sorry this bad writing , actually greppable maybe is the term.
Put ping running for a long and then try script.

I'm still not sure what you need :-(

Looking at the awk-Skript:
  # ps -efo user,pcpu,pmem,comm | grep ping | nawk 'BEGIN {s1=0;s2=0}
    {print $2,$3,$4; s1=s1+$2; s2=s2+$3}
  END {printf("Totals: %d %d\n",s1,s2) }'
you can see that the second, third and fourth field ($2, $3, $4) are being used (displayed) only.

Could you give some example input (output from "ps") and the result you'd like to see?

ps -efo user,pcpu,pmem,comm | grep sshd | nawk 'BEGIN {s1=0;s2=0}      {print $2,$3,$4; s1=s1+$2; s2=s2+$3}
  END {printf("Totals: %d %d\n",s1,s2) }'

Please see calculation error is 300%, second field is actually 3.3. It ignores numbers after comma.
