Reply: (edit)man sed: The characters \n, where n is a
digit, will be replaced by the text matched by
the corresponding backreference expression.
For each backslash (\) encountered in scanning
replacement from beginning to end, the follow-
ing character loses its special meaning (if
any). vlad

Reply: (edit)Ooops, I read it, but somehow it didn't click, or i was unable to corelate.
Sometimes just a tinkle helps. Another required now.
This works only when i use:
s/\(.*\)xyz/\1XYZ/
i.e. \(.*\)
What does this specify. Vibhor Kumar Agarwal
