OK, solved. What if a street has three or more elements as "East New York Ave"?

The sample in post#1 has trailing spaces that don't help either.

Or, more general, what separates the Cities name from the street name?

Because this is one problem where the "Hold space" capability of sed can be shown here is a solution (for one-word-cities) in sed:

Code:
sed '/^City=/ {
             h
             s/^City=//
             s/ .*/ /
             x
             p
             d
          }
     G; s/\(.*\)\n\(.*\)/\2 \1/' inputfile

I hope this helps.
