Assuming the hash is named %instructions: 
for my $computer (keys %instructions) {
  my $commands = $instructions{$computer};
  for my $comm (keys %$commands) {
    my $argument_sets = $commands->{$comm};
    for my $args (@$argument_sets) {
      my @values = @$args;
      print "$computer: $comm: [@values]\n";
    }
  }
}

That should print 
comp1: cmd2: [test2 type1 view1]
comp1: cmd1: [test1 type1 view1]
comp1: cmd1: [test2 type1 view1]

unless I made a mistake. The code is untested but looks ok to me.
