Please note that your script will probably not do the same thing under Linux and Windows.

As an example, this:

$  perl -E 'say $_ for @ARGV' m*.txt
mail_cmc.txt
modules.txt
mots.txt
...
[download]

prints the file names matching the "m*.txt" pattern under Linux, Unix or Cygwin. But it doesn't work under Windows:

C:\Users\Laurent>perl -E "say $_ for @ARGV" t*.*
t*.*
[download]

The difference is that the Unix or Linux shell will expand "m*.txt" into a list of files matching the pattern and pass the list to the Perl script, whereas Windows is too lazy to do that and just passes the pattern as you have entered.

In the latter case (i.e. with Windows, you need glob or something equivalent to expand this pattern into a list of files.

perl -E "my @a = glob(shift); say $_ for @a" t*.*
test_hash.pl
test_parl10_1.pl
test_perl10.pl
test_perl11.pl
