Hi ,

Actually the log file is like 0608166896000001 in my first column 11 whitespaces and 3001339 in my second column( 3001339) then 11 whitespaces and
3204235 in my third coumn . ...

But while reading line by line using following code

while read data
do
echo data $data
ID_SA_SOURCE=`echo $data | cut -c17-35`
echo ID_SA_SOURCE $ID_SA_SOURCE
done < $TRACKING_LOGDIR/$listdata

I am not getting the 11 white spaces in "data" variable instead of i am getting only one space..i want 11whtespaces first and 3001339 value in my ID_SA_SOURCE variable....
