La commande 'Yum' permet de nombreuses actions sur les produits Linux.
Les 2 utilisations les plus connues sont :
- L'installation de produits supplémentaires
- La mise à jour des produits déjà installé.
Pour l'installation d'un produit, il suffit de lancer la commande :
# yum install nom_produit
Le programme vérifie alors les prérequis et se connecte sur Internet pour télécharger puis installer le produit demandé.
De même, la commande suivants permet de faire une mise à jour de tous les produits installés :
# yum update
