in thread Delete reference tree from a file

So, just delete that then.

use strict;
use warnings;

use Test::More tests => 2;

my $ref = { 'servername.com' => 'foo' };
ok (defined $ref->{'servername.com'}, 'Present');
delete $ref->{'servername.com'};
ok (!defined $ref->{'servername.com'}, 'Absent');

    Thanks for the input... but here the status file contains the reference, and this has to be deleted from the file.

      The algorithm in full:

      1. Read the data from the file into a hashref.
      2. Delete the entries as desired.
      3. Write the hashref back to the file.
