Try this one:
((?:(\d{1,2}|[a-fA-F]{1,2}){2})(?::|-*)){6}
Example Usage (extract MAC address):
my $string = 'tu0 1500 <Link> 00-00-f8-05-c8-20'; $string =~ m/^.+ ( # Start back reference capture for MAC Address ((?:(\d{1,2}|[a-fA-F]{1,2}){2})(?::|-*)){6} ) # End back reference $/xms; print "$1\n" if (defined $1);
NB: This will also work with MAC like:
my $string = 'tu0   1500  <Link>  00:00:f8:05:c8:20';
