Reinstall Debian init.d scripts into default runlevels

The following zsh snippet allows you to re-install any missing startup/init.d links.

This can be useful/required when e.g. installing an upstart based distribution (like Ubuntu Lucid) has removed some of those, and you want them back after downgrading to Hardy or switching to Debian testing (like I just did).
(apt-get install --reinstall won't bring back those links; you would have to purge (apt-get purge) and reinstall the package instead, removing any other configuration of the package though)

It basically looks for any init scripts that are not present in /etc/rc?.d/S* and then looks at the packages' postinstallation script for an update-rc.d command.

It will not install anything, but only output them (and allows you to pipe it into "sh" for execution).

Worked fine on my "messed up" system, but has rather odd results on my Maverick desktop.

Code:

for i in /etc/init.d/* ; do
    a=( /etc/rc?.d/S*$i:t(N) );
    ((${#a})) && continue;
    package=$(dpkg -S $i 2>/dev/null |cut -d: -f1);
    [[ -z $package ]] && continue;
    echo "# $i: $package";
    grep "update-rc\.d $i:t" /var/lib/dpkg/info/$package.postinst;
done

(in case you need to extract the init script altogether, the following might help for starters:
dpkg-deb --extract /var/cache/apt/archives/$PACKAGE.deb /tmp/foo.)

Ubuntu Stack Exchange opened for public beta

Link: http://ubuntu.stackexchange.com/

Ubuntu Stack Exchange has been opened for public beta.

It's similar to (and driven by the same software as) Stackoverflow or Superuser: a user driven site focused on questions and answers regarding a particular topic.

While being in closed beta (to get an initial set of questions, answers and users), the Ubuntu Stack Exchange got more support than the (more generic) Linux Stack Exchange (according to Joel).

Synchronize NoScript settings using Firefox Sync

To synchronize your NoScript settings using Firefox sync (formerly known as Weave) you basically just have to enable storing the NoScript settings into bookmarks (first on master, then on slaves, after having synced).

For full instructions see the NoScript author instructions.

Useful wrappers for apt-get, apt-source and apt-file

Link: https://github.com/blueyed/oh-my-zsh/blob/master/plugins/apt/apt.plugin.zsh

I've finally started to manage the setup of my dotfiles (configuration files) for shell, editor etc.
It is based on the popular dotfiles repository of ryanb and my fork can be found at github:blueyed/dotfiles.

While I'm still in the process of setting this up, I've just added the apt-* helpers I wrote some years ago:

They provide neat things like asrc -g hardy hello to get the version of the "hello" package from hardy (via "apt-get source" and the version number grepped from "apt-cache madison" - so you need to have it in your apt sources list, of course).
Also, ashow -g testing hello will show the package from Debian testing.

Apart from that these are mostly aliases, like "aup" for "sudo apt-get update" and some of them support shell completion (of package names) for e.g. "ainst" ("sudo apt-get install"). Shell completion works in both zsh and bash (at least).

You can get the file (to be sourced in a shell) from:
https://github.com/blueyed/oh-my-zsh/blob/master/plugins/apt/apt.plugin.zsh.

Feedback is very welcome and I am sure some of this is in packages like debian-goodies already (actually, there's nothing like that in _that_ package, but..).

Does it make sense to add (parts of) it to some package for easy installation across Debian/Ubuntu?
