one liner to cleanup unused dependencies

pacman -Qdt | sed 's/ .*//' | sed -e :a -e '$!N; s/\n/ /; ta' | xargs sudo pacman -R

Hi Everyone!
I created this gigantic one liner to cleanup unused dependencies using pacman. However, I was wondering if there is a more efficient way of doing this. Anyone have any ideas?

How about

pacman -Rs $(pacman -Qdtq)

emmm, afaik you don't want to automatically loose everything listed by "pacman -Qdt"...
quick test on my system: kernel-headers? git? gnome-common?

you should fully update your system then. kernel-headers was replaced by linux-api-headers, gnome-common is in your system because was as a makedepends, i suppose git the same.

Ah, allright. My system is fully updated, and both kernel26-headers and linux-api-headers are installed. I'll just remove the kernel-headers then.

I installed git as makedepend, but still want to keep it Ok, maybe I should just work through the list and explicitly install everything important...
Still I personally would prefer sorting through the -Qdt output before removing everything.

Oh, a word of caution. That one liner I posted here uninstalled the font I was using in xterm and and anyone using it might want to check the files listed by pacman -Qdt or pacman -Qdtq before you uninstall them.

It once proposed me to remove iniscripts. It was the funniest joke arch could give me

I quite like this:

% LC_ALL=C pacman  -Qi kernel26
Name           : kernel26
Version        : 2.6.33.4-1
URL            : http://www.kernel.org
Licenses       : GPL2  
Groups         : base  
Provides       : None
Depends On     : coreutils  kernel26-firmware>=2.6.33  module-init-tools  mkinitcpio>=0.5.20  
Optional Deps  : crda: to set the correct wireless channels of your country
Required By    : None

Note the None in the required line..

@Ogion yes because you don't have any external module that depend of it. Also you omitted the most important part.

Install Reason : Explicitly installed

Yea true, wonder. I still like it
