Help with the spacing
Code:
while IFS="" read r; do
printf "XXX\t%s\n" "$r"
done < test1.txt > test.txt

The issue is, XXX wud be a dummy column/row added to the file..But i want this XXX column to be a separated as a TAB Delimiter

it should be something like

Code:
XXX    1
XXX    2

The code you have already prints tabs. I suspect the problem is extra spaces read by read, because you set IFS="". Remove that and the read command should start stripping excess spaces for you.

A shorter way may be awk '{ printf("XXX\t%s\n", $1); }' filename > outfile

Issue persists as for some files it is actually adding a dummy column as a space delimiter

Have you tried your shell code without the IFS="" ? It should strip extra spaces.
