Er, yes, you asking to replace \d+(,)\d+ with nothing, that's exactly what it does...

Try something like this (typing from memory, untested):
 
s.gsub(/(\d),(\d\d\d)/, "\1\2")

Subject: remove commas from string

I have following string:

s = "B747-400, 8,357 miles, 561 mph, 4 Pratt & Whitney PW 4056
turbofans, 56,000 lbs."

I want to remove the comma only from the numbers (8,357 miles and 56,000
lbs) separating the thousands. I want the string to read as follows:

"B747-400, 8357 miles, 561 mph, 4 Pratt & Whitney PW 4056 turbofans,
56000 lbs."

I thought this following regex would do the trick because it
successfully isolated the right commas in rubular.com

s.gsub(/\d+(,)\d+/, "")

It turns out that my regex removes the entire number, not just the
comma.

Am I wrong in saying that my regex searches for 1 or more numbers
surrounding a comma and replaces just the comma with ""?

Thank you.
