Thanks Franklin, it gives what I have requested. I need to add extra logic.
Any line which doesn't have J or R or S, at 7th position, I need to get the length lenght first and appliy logic based on lenght.

my present code which performs line by line in a loop: len=`cat firstline.txt | cut -c39-58 | tr -d ' ' | wc -m`

if len eq 9 append prakash at the end of the line followed by empty spaces as above code does..
else if lengh eq 16 append Dan at the end of the line followed by empty spaces till 256 as above code does...
else if lenth -ne 9 && length -ne 16 append Shelly at the end of the line followed by empty spaces till 256 as above code does...
-----------------
Right now I am doing line by line so there is huge performence hit.. so trying to apply the logic for all lines at once
----------------

Franklin plz help me out in giving the above logic in awk or sed....

Regards,
Jaya

	      o $offset
		- The position in $haystack to start searching

	      o $encoding
