You posted this code:

use warnings;
use strict;
use File::Basename;

my @extens = qw(.zip .dmg .tar.gz .pl .pl~ .cgi .mp3 .txt);
my @ppal;
my $i = 0;

foreach my $arch (@ARGV ){
    my ($name,$path,$suffix) = fileparse($arch,@extens);
    $ppal[$i] =    [];
    push @{$ppal[$i]},($path,$name,$suffix);
    $i++;
}

foreach    my $elem (@ppal){

    print "Path:\t@{$elem}[0]\tArchivo:\t@{$elem}[1]\tExtens:\t@{$elem
+}[2]\n";

}

It could use some cleanup:

use warnings;
use strict;
use File::Basename;

my @extens = qw(.zip .dmg .tar.gz .pl .pl~ .cgi .mp3 .txt);

my @ppal;
foreach my $arch (@ARGV) {
    push @ppal, [ fileparse($arch, @extens) ];
}

foreach my $elem (@ppal) {
    print "Path:\t${$elem}[0]\tArchivo:\t${$elem}[1]\tExtens:\t${$elem
+}[2]\n";
    #or: print "Path:\t$elem->[0]\tArchivo:\t$elem->[1]\tExtens:\t$ele
+m->[2]\n";
    #or: printf "Path:\t%s\tArchivo:\t%s\tExtens:\t%s\n", @$elem;
}

To introduce map, change

my @ppal;
foreach my $arch (@ARGV) {
    push @ppal, [ fileparse($arch, @extens) ];
}
[download]

to

my @ppal = map { [ fileparse($_, @extens) ] } @ARGV;
