Anonymous Monk seems to have the right idea: Just load the
whole database into a hash, increment the user element (it will be created if non-existant), and save the whole thing
overwriting the file.
If the user database gets too large to be handy, an upgrade
would be to tie the hash to a database of some kind. There is one that seems universal to perl installations. ( NDBM? )
use NDBM_File;
tie(%x, 'NDBM_File', 'karma.db', 1, 0);
$x{$user}++;
untie(%x);
Here the hash keys and values are maintained in the database
and some subset is also maintained in the hash itself, but
elements are transferred implicitly from the database to
the hash (and vice-versa) as needed. The 'untie' line puts all new and changed elements out to the database.
That last paragraph is clear as mud, hmm..
