Hi. Try this:

my %hash = ( key1 => 'value1',
key2 => 'value2',
key3 => 'value3',
key4 => 'value4');

open OUT," > file.txt" or die "$!\n";

while (my ($key, $value) = each %hash) {
print OUT "Key: $key , Value: $value\n";
}
close OUT;
Enough ?

how could yOu read them from file.txt and store in memory again?
is there a binary format for hash?

There are several modules on CPAN for serializing arbritrary data
structures. One of them is Storable. Another is Data:umper.

sorry, what did you mean by that? there is an alternative usenet
newsgroup for perl? I frankly found the traffic here a bit low given the
popularity of perl.

On one USENET server, this bogus newsgroup of comp.lang.perl has
only 459 articles online. The proper newsgroup comp.lang.perl.misc
has 3146 articles online. Go there for more info.
