in thread Generation of Array of hashes by reading a file

Thanks Huck and other Monks. All the solutions work. One of the doubt I had with this, Every time when the line matches the key related to interface, we are making the hash empty and then pushing that on to Array. I was assuming the Array will only contain a list of empty hashes, But not the case when I run the script with your solution. Can you please explain or help me understand the push statement after assigning empty hash to rec

    $rec is not a hash, it's a hash reference. When you change the referenced hash, all references pointing to it see the new value.

    my $hash_ref = {};
push my @arr, $hash_ref;
$hash_ref->{key} = 'value';
print $arr[0]{key};  # value
