First, you need to be aware that it is your *nix shell that is doing the glob expansion. If you don't want it to do that, then you'll need to use your shell's quoting rules (e.g. -ts "*.vh").

Second, the perl-thing you might want to look at is the Getopt::Long module. Using this (standard) module, you can process your options as:

  use Getopt::Long;

  my @cfg_files;
  my @ts_files;

  GetOptions("cf=s@" => \@cfg_files, "ts=s@" => \@ts_files);

Perl will then extract the args into the arrays for you. (but don't use the shell-quotes in this case) --Dave.
