Awk itself iterates over the file....so no need to loop through each of the lines...

About the set of operations...There is no restriction on no.of commands...

refer below...some more set of operations...on NR==1

Code:
awk -F" "  'NR==1{val=$2;print val + 1000, val*2}' file

Hope this explains and help...Smilie

for(i=1;i<=3;i++)
do
Index=`awk 'NR=='$i' {print $2}' input`
value=Index+3000
echo $value

Thanks to all of u
