Utilitaire de recherche de paquets installés: listpkg

Contributeur: Wedge

C'est tout simple, une fois le script copié dans un répertoire du PATH (genre /usr/bin ou /usr/local/bin par exemple), il suffit de lancer dans une console:

[wedge@chimaera ~]$ listpkg ripdvd
ripdvd-1.12.1-noarch-1wed.tgz

Le paramètre est analysé par le script qui recherche tous les paquets contenant ce “mot” dans leur nom. Les paquets correspondants sont ensuite listés sur la console.

Il est tout à fait possible de ne mettre qu'une partie du nom, ou même d'utiliser une expression régulière avec l'option -e
