Regex - get first occurrence

Question

I have the following string:

EN=sdfsdf, CN=User Name, CN=Users, DC=domain, DC=co, DC=il

I need to return the first string that starts with "CN=" and ends with an ",". In this case I need to return "User Name".

'CN=.*,' returns "CN=User Name, CN=Users, DC=domain, DC=co,"

How can I get the just the first occurrence?

Don't use the global flag `g`. Depending on your programming language, you may need to use the regex matching function that only matches once (i.e. PHP's `preg_match` instead of `preg_match_all`) — ctwheels, Jan 17 '18 at 14:46

You will need the non-greedy option in your Regex:

CN=.*?,
