I didnt know which reply to reply to, so ill just reply to myself haha ;) Anyway, i did change up the module and script a little, to this:

#Package.pm

package My::Package;

use strict; #can use strict and warnings as usual now as well without 
+any warnings
use warnings;
use Exporter qw(import);

our @EXPORT = qw(print_lines test test_2); #just add in function names
+ as you make them
our %EXPORT_TAGS = (all => \@EXPORT);


sub print_lines{

    my ($input) = shift;

    while(<$input>){
        print;
    }
    close($input);
}


sub test{
    
    my ($input) = shift;
    print $input;
}

sub test_2{
    
    my ($input) = shift;
    print $input;
}

And here is the script calling it

#script.pl

use strict;
use warnings;

use My::Package qw(:all);


open (my $file, '<', shift);

print_lines($file);
test("hello world\n");
test_2("hello this is dog"); # i love this meme lol

That ":all" is what i was originally shooting for. Though I also figured out you could just require My::Package; and then just call it in the script with use My::Package; and do not have to specify any functions. Anyways, thanks for the help fellers :)

UPDATE: Also I wanted to ask, if I use strict and warnings in the main script, is that in the modules scope as well, or do I need to use strict and warnings in the module as well? Also IF strict and warnings are in the same scope, is it just for the functions/subs or the whole module?
