Hi,

Now i need the 2nd column value get printed
I tried with the following command

awk 'NR==1 {print $2}' input
this works fine for only 1st row.I need to change always NR assigned value to get printed all the 2nd column values so i tried like this but i m not getting

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

But i am not getting any value printed
Please anyone help me in this ...
