You mean "global", not "greedy"
Two snippets from the perl documentation:
s/PATTERN/REPLACEMENT/egimosx
Options are:
e Evaluate the right side as an expression.
g Replace globally, i.e., all occurrences.
i Do case-insensitive pattern matching.
....
-- and --
By default, a quantified subpattern is ``greedy'', that is, it will match as
many times as possible (given a particular starting location) while still
allowing the rest of the pattern to match. If you want it to match the minimum
number of times possible, follow the quantifier with a ``?''. Note that the
meanings don't change, just the ``greediness'':
*? Match 0 or more times
+? Match 1 or more times
