[TriLUG] vi question

[Greg Brown]

I'm trying to match multiple commas in a line in vi so I can globally change
them to a single comma (yup, I'm building a .csv file).

Here's an example line::

,101.5000,WRAL,,,,,,,,,,,,,,,,,,,,,,Raleigh,,,,,,,,,,,,,,BF,,,,,,,,,,,,,,,,,,,,,,,Rock

The leading comma is ok, I really don't care about that, it's easy enough to
strip out.

:1,$s/\,+/\,/g  is NOT working.  Grr.  Any hints?  I know I'm overlooking
something extraordinarily simple here....
