将哈希写入文件的最佳方法

Storable

 use Storable;
 store \%hash, 'file';
 my $hashref = retrieve('file');

BerkeleyDB

use BerkeleyDB;
use MLDBM qw(BerkeleyDB::Hash) ;
use Storable;


my $env = BerkeleyDB::Env->new(-Home => $home);
tie %store, 'MLDBM', -env => $env;

$store{my_stored_hash} = \%hash;

use Fcntl;
use SDBM_File;

tie(%h, 'SDBM_File', 'filename', O_RDWR|O_CREAT, 0666) or die $!;
...
...
untie %h;

tie dbmopen

open(OUT,">myFile.txt");

foreach my $key (sort keys %hash) {
   print OUT $key.",".$hash{$key}."\n";
}
close(OUT);
