iostat

Hi all,
I want to run "iostat -xnmpztc 2 5 and delete first 4 set of "extended" stats and print only 5th set.

Please suggest!

If you want to display the 5th line of the output of a command, you can use a mix of head and tail commands. For example:

Code:

seq 7|head -5|tail -1

FYI, I did not do it with your iostat command because those options don't work on my system

no i don't want to display the 5th line ,i want to display the complete 5th set

iostat -xnmpztc 2 5

This will show the fifth set:

Code:

iostat -xnmpztc 2 5 | nawk '
/extended device statistics/ { if(++i>4) { j=1} }
{ if(j==1) print }'

thanks it worked but i need the output as

tty cpu
tin tout us sy wt id
0 99 2 1 0 97
extended device statistics
r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device
1.0 4.0 4.0 25.9 0.0 0.0 0.0 0.8 0 0 c0t0d0
0.0 3.0 0.0 23.9 0.0 0.0 0.0 1.1 0 0 c0t0d0s0 (/)
1.0 1.0 4.0 2.0 0.0 0.0 0.0 0.3 0 0 c0t0d0s7 (/export)

instead of

extended device statistics
r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device
1.0 4.0 4.0 25.9 0.0 0.0 0.0 0.8 0 0 c0t0d0
0.0 3.0 0.0 23.9 0.0 0.0 0.0 1.1 0 0 c0t0d0s0 (/)
1.0 1.0 4.0 2.0 0.0 0.0 0.0 0.3 0 0 c0t0d0s7 (/export)

Just replace "/extended device statistics/" by "/tty cpu/" in my script. By the way, please use code tags when posting code and command output. This ease readability.
