ruby - Extract text before first comma with regex

Question

I want to extract text before first comma (first and last name) from strings like:

John Smith, RN, BSN, MS
Thom Nev, MD
Foo Bar, MD,RN

I tried with regex:

(.*)s(.*),s

but this doesn't work for all situations. How to achieve this?

Answer 1

Match everything from the beginning of the string until the first comma:

^(.+?),
