Hi fellow Monks, I am reading a code that somebody wrote and I am trying to make sense of it.

What does it mean if they pass a ($) or ($$) to a subroutine?

For Example::

sub mysub1($)

sub mysub2($$)

PLEASE NOTE I DIDN'T WRITE THE WHOLE CODE INSIDE, BUT IT IS A SUBROUTINE

WHAT DOES $ STAND FOR?
