Hi, I have been looking but I haven't found a solution to check if a given file in my system belongs to any of my Installed packages. For example, in all my 3 archllinux machine I have a directory named: /usr/lib/libreoffice/basis3.3 85Mb I would not expect to have this directory as I'm fully updated and my current libreoffice is 3.4. Accordingly there also exists the directory: /usr/lib/libreoffice/basis3.4 335Mb I'm not an expert in the libreoffice package and therefore blindly removing the first, without knowing if it is really needed or it is just some directory during the updates, makes me feel unconformable. The command in question should be able not only to check repository packages but also locally installed ones although if it is not possible with the first will be enough.
