[arch-general] Pacman: Remove unneded dependencies

[L. Rose]

Hi,

I know, this is probably a very common question, but I couldn't find any
information on the pacman wiki article about that, so I have to ask. How
can I uninstall all packages on my system, which have been installed as
a dependency, and aren't needed any longer? (Because I've uninstalled
the dependent package or because the dependent package no longer depends
on that dependency)

I've read about pacman -Qe, but this lists packages I've explicitly
installed and don't want to remove. And please, don't just point to the
wiki article, I've checked that already.

Thanks in advance,

Lukas

Not enough apparently, because it’s in it.

You’ve also got --help and the man page to help you. ;)

Check again under
https://wiki.archlinux.org/index.php/Pacman#Querying_package_databases
(look for "orphan").

Best,

Hi,

you've got a German email address, perhaps this Wiki does help:

https://wiki.archlinux.de/title/pacman#Anwendung

Take a look at

"pacman -Rs [paket] Paket mit allen benötigten Abhängigkeiten
entfernen (wenn diese nicht von anderen
installierten Paketen benötigt werden)

pacman -Rss [paket] Paket mit allen benötigten Abhängigkeiten
und deren Abhängigkeiten entfernen"

Regards,
Ralf

PS: To see if a package is needed by another package

pactree -r

could be useful.
