Subject: How to find multiple matches in a string

I know how to use regular expressions to find the first match of a
pattern in a string.  But, how do I most easily find multiple matches?
For example, if the string is

s = 'abcde_abcde_abcde'

and I want to find the location of ALL the 'b' characters, how do I do
it?  If I use

m = s.match(/b/)

then m.offset(0) => [1,2]

but I don't have any information about the second or third occurences of
'b'.
