L'installation d'un logiciel passe par la commande emerge. La commande equery est un bon complément à emerge. Cette section présente les facettes les plus courantes de leur utilisation.

Information !
Lors d'une installation vous pouvez obtenir beaucoup d'information sur l'installation en cours en rendant la commande emerge plus bavarde. Ajoutez le paramètre --verbose à la requête d'installation.

Installation standard

La forme la plus simple d'une installation est celle-ci :

# emerge paquet

Prévisualisation d'une installation

L'installation d'un paquet entraîne souvent l'installation d'autres paquets qui en forment ses dépendances. Pour savoir exactement ce que vous installerez, utilisez le paramètre --pretend.

# emerge --pretend paquet

Une liste de tout ce qui sera installé s'affichera. Aucune installation n'a lieu. Pour procéder à l'installation, reprenez la commande sans le paramètre --pretend.

# emerge --pretend vlc

These are the packages that would be merged, in order:

Une autre façon de faire est l'utilisation du paramètre --ask. À la fin de la liste des paquets qui seront installés, une question est posée. Vous répondez par oui (y) ou nom (n) selon que vous désirez installer ou non le paquet.

# emerge --ask paquet

# emerge --ask vlc

Would you like to merge these packages? [Yes/No] n

Quitting.

La suppression, désinstallation, d'un logiciel se réalise avec l'option unmerge de la commande emerge.

Attention !

Portage ne vérifie pas si le paquet à supprimer est requis par un autre paquet. Par contre Portage avisera quand la suppression du paquet risque de casser le système.

Soyez prudent.

Pour palier aux mauvaises surprises, effectuer une vérification avant de supprimer un logiciel.

Vérification avant suppression

En supposant que le paquet à supprimer est xchat, voici comment procéder à une vérification avant une suppression.

# emerge --pretend --verbose --depclean xchat

Calculating dependencies... done!
>>> Checking for lib consumers...

>>> These are the packages that would be unmerged:

 net-irc/xchat
    selected: 2.8.6-r1 
   protected: none 
     omitted: none 

>>> 'Selected' packages are slated for removal.
>>> 'Protected' and 'omitted' packages will not be removed.

Packages installed:   623
Packages in world:    67
Packages in system:   58
Required packages:    622
Number to remove:     1

Suppression

Pour supprimer un paquet :

# emerge --ask --unmerge xchat

Le paramètre --ask permet de vérifier deux fois plutôt qu'une avant de désinstaller un logiciel.

 * This action can remove important packages! In order to be safer, use
 * `emerge -pv --depclean <atom>` to check for reverse dependencies before
 * removing packages.

>>> These are the packages that would be unmerged:

 net-irc/xchat
    selected: 2.8.6-r1 
   protected: none 
     omitted: none 

>>> 'Selected' packages are slated for removal.
>>> 'Protected' and 'omitted' packages will not be removed.

Would you like to unmerge these packages? [Yes/No]

Répondez par oui (Y) ou non (N) pour désinstaller ou non le paquet.

Lorsqu'un paquet est supprimé, les dépendances de celui-ci ne le sont pas. Les dépendances sont les paquets automatiquement installés par l'installation d'un paquet. Ces dépendances sont donc des orphelins par rapport au paquet désinstallé. Pour les supprimer, ayez recours à la fonction -depclean de la commande emerge.

# emerge --depclean

Pour éviter que la suppression des dépendances entraîne un dysfonctionnement du système, veuillez réparer d'éventuels liens brisés une fois l'opération --depclean terminée.

# revdep-rebuild --ignore
