hi
Hello,
in the below script:
use Storable qw(store_fd fd_retrieve);
my %position_counts = ('name' => 'rahul');
open(OUT1, ">temp.txt");
store_fd(\%position_counts, *OUT1) || die "can't store to temp.txt\n";
close(OUT1);
is it possible to change values of my hash "%position_counts" stored
in the file without retrieving it back using "fd_retrieve"?
if its not possible can you tell me how to store a huge hash data
to a file or dbm and edit it without retrieving it back in perl.
Is "storable" module the best option?
As long as the hash values are simple scalars and not references or
filehandles then you could use one of the DB modules:
perldoc DB_File
perldoc GDBM_File
perldoc NDBM_File
perldoc ODBM_File
perldoc SDBM_File
perldoc perldbmfilter
