Title: Hash_Of_Arrays Question

First, the hash assignment should be

 

%hash1  = {
                        directory1                      => [ files ],
                        directory2                      => [ files ],
                        directory1_subdirectory1=> [ files]
                  }; 

 

# Then you can copy it with

 

%hash2 = %hash1;

 

# this should be a true copy, where changes made to one would not affect the other

# but if you did truly want a hash ref:

 

$hash_ref = \%hash1;

Subject: Hash_Of_Arrays Question

I am having a Hash_Of_Arrays data structure:

$hash1  = {
                        directory1                      => [ files ],
                        directory2                      => [ files ],
                        directory1_subdirectory1=> [ files]
                  };

Now, I need to "clone" another hash to the results so that there is a "copying" of exact contents. I know that an assignment of :

$hash2  = $hash1;

would assign a reference, which means anytime I mess with $hash2, the contents of $hash1 would get changed.

Question: How would I "clone" $hash1 to $hash2, efficiently?

Thanks,
Rex
