simple awk sort problem

Shell Programming and Scripting

Hello folks

I have the following output

UNIX95=1 ps -ef -o pcpu,user,pid,args |more
 %CPU USER       PID COMMAND
 0.03 root         0 swapper
 0.08 root         1 init
 0.00 root        13 net_str_cached
 0.00 root        12 usbhubd
 0.00 root        11 escsid
 0.00 root        10 ttisr
 0.02 root         9 ksyncer_daemon
 0.00 root         8 ioconfigd
 0.00 root         7 kai_daemon
 0.04 root         6 kmemdaemon
 0.00 root         5 signald
 0.00 root        14 net_str_cached

I would like to keep the first line (NR==1) and the sort on the cpu (first)field
Would this be possible with awk ??

TIA

Don't think awk is really applicable here.

UNIX95=1 ps -ef -o pcpu,user,pid,args |
        (       head -n 1
                sort -n )
3

try like this

UNIX95=1 ps -ef -o pcpu,user,pid,args | /bin/sort -r|sed -n '1,12p'
4 
UNIX95=1 ps -ef -o pcpu,user,pid,args | (head -n1; sort -r -k 1,1) | head -10
 %CPU USER       PID COMMAND

Thank you very much but there seems to be an undesirable output line:

f /u1/rjl/db.pf -p gnpr/gnmenum -q -mmax 1024

I think this is the very last line from the original command .. any idea as to how to suppress it ??
Thnx again !!
