Re: Automatic removing of unneeded .deb files?

[Eric Cooper <ecc@cmu.edu>]

Here's an alternative way to do it, by scanning the .deb files and
seeing if they're already installed or not.  (It's in bash, but should
be easy to convert to Python etc.):

    #!/bin/bash

    for deb in /var/cache/apt/archives/*.deb; do
	pkg=$(dpkg-deb -f $deb Package)
	if ! dpkg-query -Wf '${Status}' $pkg | grep -q ' installed'; then
	    echo $pkg: not installed
	    # uncomment this to remove it ...
	    # rm $deb
	fi
    done
