Use Tim's approach but modify the replacement using:

Thanks for the link. It certainly solves my problem. However, I have
one question related to the solution given there.
:let i=1 | g/foo/s//\="blah_".i/ | let i=i+1
When I run the above, I see that it replaces 'foo' (the first
occuerence in a line) with blah_1, blah_2, etc., as the tip claims to
do. But I am not very clear on the three separate steps in the
process. On first looking at the above command, my understanding was
that first we are assigning 1 to i, then running the substitution
command over the entire file and then incrementing i -- which is not
correct because then the file will have all 'foo' replaced only by
'blah_1' and i incremented only once at the end. So looks like the
middle step (substituation) is not an atomic step and rather an
(implicit) iterative step. Can someone explain this behavior of the :g
and :s command in slightly greater detail or point to some explanation
on the same?
Actually, what happens is that the second | does not separate the :g
command from the :let command, but :s and :let _within_ the :g command,
see :help :bar (and notice that :global i.e. :g is in the list of
commands which see | as part of their argument).
Best regards,
Tony.
