Trucs de geek : dmidecode

La commande dmidecode est un outil pour afficher le contenu de la table DMI (SMBIOS) dans un format lisible par l'homme. Cette table contient la description des composants matériels mais aussi d'autres informations utiles tels que le numéro de révision du BIOS.

Avec dmidecode vous obtenez toutes ces informations en une commande. Sous Ubuntu saisissez :

# sudo dmidecode

et vous obtenez :

# dmidecode 2.12
SMBIOS 2.6 present.
