Need to extract data from Column having variable length column

Hi ,

I need to extract data from below mentioned data, having no delimiter and havin no fixed column length.

For example:

Member nbr Ref no date
10000 1000 10202012
200000 2000 11202012

Output:

to update DB with memeber nbr on basis of ref no.

I tried to count the number of character between Member ..... Ref
but not able to get into result .. anyone can help on same

I don't understand. What is the exact output you're looking for?
Code:
echo "0000          1000     10202012" | awk '{print $1}'

i have three columns in below format which contain space and similarly i have ulitple spaces between these column where evr i tried to extract 1 st column
with below command:
awk '{print $1}' it not working because i have space in coulmn name

1. Member nbr
2. Ref no
3. date

i need to extract refno in such a way i will parse from starting with 'R ... to 'd' and count the no. of charcter and on baisi of that count i will extract ref no.

Your problem is that the first line (column titles) contains spaces in column names?

If you need to treat the headers separately I suggest s substitution of /\s+(no|nbr)/_$1/ on reading the first line.

I tried substitution command but it is not working
Code:
> echo "Member Nbr" | sed 's/\s+(no|nbr)/_$1/'
> Member Nbr
