现在我的file1包含哈希哈希,如下所示:

package file1;

our %hash = (
    'articles' =>  {

                       'awk' => '9 awesome articles posted',
                       'sed' => '10 awesome articles posted'
                   },
    'ebooks'   =>  {
                       'linux 101'    => 'Practical Examples to Build a Strong Foundation in Linux',
                       'nagios core'  => 'Monitor Everything, Be Proactive, and Sleep Well'
                   }
);

#!/usr/bin/perl

use warnings;

require 'file1';

my $key;
my $key1;

for $key (keys %file1::hash){
   print "$key\n";

   for $key1 (keys %{$file1::hash{$key1}}){
   print "$key1\n"; …
