Cleaning up the package cache

evdvelde · 2006-03-21 12:57:25

Hi,

for me, the pacman -Sc and pacman -Scc calls are too primitive to do what I want to do. e.g. pacman -Sc removes outdated packages, but not packages removed from the system (and still up to date with the repository). Therefore I have written the following tiny script: it removes all packages that are not currently installed or are outdated and then it downloads all packages you have installed (in case you want to have a complete cache of all installed packages).

#!/bin/bash

pacman -Sc

pacman -Q | sed s/' '/-/g > /tmp/installed


for pkg in `ls /var/cache/pacman/pkg`
do
        name=${pkg%%.pkg.tar.gz}
        if [[ ! `grep $name /tmp/installed` ]]
        then
                echo Removing $name
                rm -f /var/cache/pacman/pkg/$pkg
        fi
done

pacman -Q | cut -d ' ' -f 1 > /tmp/installed
pacman -Sl | cut -d ' ' -f 2 >> /tmp/installed

pacman -Sw `sort /tmp/installed | uniq -d`

It is still basic, but feel free to comment on it

I haven't tried it yet but I like the idea. Good work

The mysterious world of computers... it does not happen with me. I'll have a look at it.
