in reply to Passing parameters to scripts

All command line parameters are stored in @ARGV array. So you can access it directly like:

my $file = $ARGV[0];

or even like this (modifying the array):

my $file = shift @ARGV;

However if you need only to pass a file name as a parameter for opening it at a later stage, you can say

while(<>) { }

straight away and this will read from the file on the command line.

If you want to pass complex things on the command line (like options, etc), have a look at a module Getopt::Long

And no, I don't think there is any difference in Unix and Windows in this respect.

Just my 2 Lithuanian cents.

    There are differences in how the various shells interpret certain symbols, so what you may need to use for one shell might not work in another. For instance in *nix arguments are normally globbed by the OS, wheras in Win32 they are normally globbed by the program. Other difference would be quoting characters and escape rules.
