Hello Amos,
I am trying to find and match "abc123" only, cache-1 , cdn-1 ,
videos-1 .
but s/([a-z]*+[0-9]*)/cdn/; is also matching words without digits!!
That is what '*' means. ZERO or more of the token to its left.
It will also match "123" without letters.
*+ is a bit weird. It means ONE or more copies of token with ZERO or
more letters.
ie one empty string might match.
I want to match for example ...
http://(a1.domain.com) not (a.domain.com) so how to restrict it more
!!?
s/([a-z]+[0-9]+)/cdn/
