DumpGDBM

GNU dbm (ou GDBM, en abrégé) est une bibliothèque de fonctions de base de données qui utilise un hachage extensible, une association key/value persistante.

https://en.wikipedia.org/wiki/DBM_(computing)

Exemple

Le mini-script Perl exemple.pl montre bien comment faire une "base de données associative" en Perl. Il extrait les champs usernale et GECOS du fichier /etc/passwd et les injecte dans un fichier gdbm.
