How to read back a file written using Data::Dumper (but not with the default VAR naming)?

I have written a hash structure into a file using 

print FILE Data::Dumper->Dump([$x], [ qw(*x) ]);

How do I read this back from file? If I use eval as shown in the following snippet, all I get is $VAR1 = undef;

local $/; $hash_ref = eval <FILE>;
Solution

  • You can use the core module Storable to do this type of task.

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