Greedy Matching
<<<< ^^^^^ >>>>

Regex matches as early as possible

Regex matchs as long as possible

Perl Example: Try to list all "w.*ll" --

#!/usr/bin/perl
print "\n\n\n";
$str="the well water in lower walla walla will be wonderfull now";
print "===" . $str . "===\n";
@hits = ($str =~ /w.*ll/g);
print "->>" . join(":::", @hits) . "<<-\n";
