How to restore a single file from a package?

How can I do this without reinstalling the rest of the files as well?

    Download the package, for example transmission-daemon, with

    sudo apt-get --download-only install transmission-daemon

    unpack the package with

    mkdir ~/dummy
dpkg-deb -x /var/cache/apt/archives/transmission-daemon_*.deb ~/dummy

    restore the file, for example /etc/init.d/transmission-daemon

    sudo cp ~/dummy/etc/init.d/transmission-daemon /etc/init.d

    remove the dir

    rm -rf ~/dummy

  2. I know this is a bit old, but here's my improvement:

    $ sudo apt-get download <package-name>

    instead of

    $ sudo apt-get --download-only install <package-name>

    I had a situation where the package was already installed (hence, the proposed solution didn't work), and I wanted to restore just one config file, in order to fix the problem.

    Cheers
