Remove all packages except 'base' group

quack · 2010-01-18 08:43:35

hello,

I have one question. Is it possible to remove all the packages except those in base, 'cause I want to have a clear system and don't want to reinstall my arch.

Thanks for reply.

Untested....

base=$(pacman -Sqg base | sort | uniq)
installed=$(pacman -Qq)   
remove=$(comm -13 <(printf "%s\n" "${base[@]}") \
            <(printf "%s\n" "${installed[@]}"))
pacman -R ${remove[@]}

There's a way with a command I don't remember.

But it's somewhat like this:

pacman -Rscnd ${<command>}

Umm, that's almost bound to end in disaster eventually...

Have a look at this post: http://bbs.archlinux.org/viewtopic.php? … 34#p687234

the post shows:

pacman -Qgq base base-devel # all packages in groups base and base-devel, add more if you want
pacman -Qetq # all packages explicitly installed

pacman -Qetq | fgrep -vxf <(pacman -Qgq base base-devel)

=========================================

comm -23 <(pacman -Qetq) <(pacman -Qgq base base-devel xorg | sort)

Now, is there a way to also remove all left over files in the system not belonging to these groups? I'm glad someone brought up this topic, I've been wondering about cleaning the system out without doing a fresh install.

same here it would be awesome if all config files an also be purged (other than home directory)

To purge config files you just re-install base. That's how I resolved a kernel panic that I had...
