Hi
use strict;
use Fcntl ':flock';
use DB_File;
my %temp;
my $db = tie %temp, 'DB_File',$easylist, O_CREAT|O_RDWR, 0666, $DB_HASH
or die "Could not tie hash:$!";
##### Exclusively lock the database to ensure no one access it
my $fd = $db->fd();
open DATAFILE, "+&<=$fd" or die "Cant safely open file: $!\n";
flock( DATAFILE, LOCK_EX) or die "Unable to acquire lock $!. Aborting";
close the database
undef $db;
untie %database;
### Close the filehandle to release the lock
close DATAFILE;
