Something like this?

#! perl -lw
use strict;
use Data::Dumper;

BEGIN{
    our %channels;
    my $channel;
    while( @ARGV ) {
        $_ = shift @ARGV;
        $channel = shift @ARGV and next if m[-channel];
        $channels{ $channel }{ $1 } = shift @ARGV and next if m[-([a-z
+])];
        die "Invalid arg '$_'";
    }
}

our %channels;
print Dumper \%channels;

Yes but I'm intrested in storing the values in some variables, exactly in this way proposed by you how can i call the value for 'c' from '2' for eg? Thanks again, bory

how can i call the value for 'c' from '2' for eg?

You are new to perl? The following will print the value of 'c' for channel 2:

print $channels{2}{c};

Hello, I come back with almost the same problem, using your code for this command line synthax:

456642 -channel 1 -a 1 -b 1 -c 1 -channel 1 -a 2 -c 2 it prints only
$VAR1 = {
            '1' => {
                   'c' => '2',
                   'a' => '2'
                 }
        };

but I want to print also the first values for channel number 1, like this:

$VAR1 = {
          '1' => {
                   'c' => '1',
                   'a' => '1',
                   'b' => '1'
                 },
          
          '1' => {
                   'c' => '2',
                   'a' => '2'
                 }
        };

Thank you for your time, bory

Hash keys are unique. You cannot have 2 identical keys in the same hash. You would have to use some other data structure to represent your data. Maybe an hash of arrays of hashes?

$var = {
    1 => [
       { a=>, b => 1, c=> 1 },
       { a => 2, c => 2 }.
    ]
};

That said, how can channel.1.a be both 1 & 2?

I'm not party to your application details, but that really doesn't make a lot of sense to me.
