Friends, I have a awk script which will calculate values for columns which is working fine in linux but failing in solaris.
here is my awk script

iostat -dt $INTERVAL $ITERATION | awk 'NR>4' | egrep -v "Linux|Device|Time|AM|PM|sda[0-9]" | awk '{if(/^$/){printf("%f \n"
,sum); sum=0}else{sum+=$2}}
but a similar thing is failing on solaris

here is the script on solaris

sar -d 2 2 | sed -n '/Average/!p;/Average/q;' | egrep -v "nfs[0-9]|device"|awk 'NR > 2 { if ($1 !~ /,.+/) print }'|

awk ' {if(/^$/){printf("%f \n"
,sum); sum=0}else{sum+=$2}} '
.

Can any one pls clarify why its failing in solaris and whats the remedy
