in thread Regex substitute matches second match first?
The /g modifier is for global matches. For instance, if you had numerous IPs on a single line, and you wanted to grab them all. eg: (untested)
my $line = "1.1.1.1 blah 2.2.2.2"; my @ips = $line =~ /\d+\.\d+\.\d+\.\d+/g;
Now $ips[0] would be '1.1.1.1' and $ips[1] would contain '2.2.2.2'.
A couple of docs you can review are perlretut and perlre.
