iostat script for AIX

[made13]

Hi,

The following command outputs the iostat info on a AIX server;

# date; iostat -d | head -2; iostat 2 2 | grep hdisk | sort -n

I want to exclude the first set of figures for the hdisks, as this is the cummulative figure since system initialization. Is there a way this can be done?

Try something like this:

(date;iostat -d | head -2;iostat 2 2 | grep hdisk | sort) | awk '
/^hdisk/{a[$1]++;if(a[$1]==1)next}
{print}'

Hope This Help
PH.
