Guide HWINFO

Objet : Obtenir de l'information sur les composants matériels d'un ordinateur avec l'utilitaire hwinfo.
Niveau requis :
débutant, avisé
Commentaires : Utile pour le dépannage, le soutien technique et la configuration du noyau.
Débutant, à savoir : Utiliser GNU/Linux en ligne de commande, tout commence là !.

Introduction

L'utilitaire HWINFO est conçu pour explorer les composants matériels d'un PC. L'information générée est fort utile pour du soutien technique. On peut s'en servir comme référence lors de la configuration du noyau. Si vous ne trouvez pas tout ce que vous cherchez sur l'usage de la commande, consultez le manuel pour en savoir plus.

man hwinfo

Utilisation

Cette section du tutoriel se divise en plusieurs sous-sections, chacune présentant un aspect précis de l'usage de la commande hwinfo.

La commande hwinfo oblige son exécution avec les droits d'administrateur (root).

Les informations générées par la commande hwinfo peuvent être enregistrées dans un fichier journal. Utilisez l'option --log suivi du nom du fichier où sauvegarder le résultat.

Il s'agit d'exemples. L'information obtenue variera selon votre configuration matérielle.
