Comment retrouver le nom d’un paquet.
Je ne sais pas si vous êtes comme moi, mais la mémoire me fait défaut parfois. Pourtant, bien souvent nous avons besoin de retrouver le nom d’un paquet installé.
L’option -S nous permet d’effectuer cette recherche avec l’outil dpkg, nous allons rechercher le paquet qui a fournit l’utilitaire « korn »
pascal@pascal:~$ dpkg -S korn

Mais il existe une autre méthode avec dlocate. S’assurer que dlocate est installé sur votre machine, sinon aptitude install dlocate en root.
Puis
pascal@pascal:~$ dlocate korn
