Hi monks,

I'm searching a way to insert colons into a mac address in the format:

525400eb8b36

to get:

52:54:00:eb:8b:36

one way is this:

$mac = join(":", /^([0-9a-fA-F]{2})([0-9a-fA-F]{2})([0-9a-fA-F]{2})([0-9a-fA-F]{2})([0-9a-fA-F]{2})([0-9a-fA-F]{2})$/);

but it's _very_ ugly.

This also works: $mac = join(':', unpack('A2A2A2A2A2A2', $_));

but I would prefer a regex; is there a way to make the regex above more compact?

How would you perform this tasK?

Thanks,
bye.
