Keeping arch system clean

Hi archers,
what do you do to keep your system clean? You surely have / had orphan packages, or packages no more used, so i was wondering what operation you perform to check for installed useless packages and remove them from the system, to keep your arch clean and slim everyday!

Re: Keeping arch system clean

I run this daily after an update (pacman -Syyu), works for me.

#!/bin/bash

tar -cjf /store/bak/pacman-database.tar.bz2 /var/lib/pacman/local
pacman -Rscn $(pacman -Qtdq)
pacman -Sc
pacman-optimize && sync
updatedb

exit 0

Re: Keeping arch system clean

I use these 2 aliases in my zshrc, got them off the forum or wiki a long time ago.

alias lsorhpans='sudo pacman -Qdt'
alias rmorphans='sudo pacman -Rs $(pacman -Qtdq)'

Re: Keeping arch system clean

my update script checks for and removes orphans once the update is done so as I update at least once a day then the system should be always clean.

The idea by droog above is slick

Re: Keeping arch system clean

A couple of questions:  With the scripts above how do you prevent it removing needed packages.  For example, in my case it would remove gksu which I use.  Also, I can run "pacman -Qdt" as a normal user, so why is the sudo required?

Install the package explicitly:

pacman --asexplicit -S gksu

Re: Keeping arch system clean

loafer got there before me - droog's second command wants to wipe some 800MB off my system, most of which I appear to use all the time (kde-pim being a particularly important candidate). Methinks I don't fully understand pacman. Correct that, meknows I don't fully understand pacman smile

I have a couple of question about your script.
1. What is the utility of the sync and updatedb commands? As far as I see they're not related to pacman.
2. Wouldn't run pacman-optimize before an update be more useful?
3. Do you always remove your packages with the -c option? Isn't this dangerous?

Thanks! smile

The sync just makes sure that everything is written to physical media, the updatedb because I call this script after an update script, so I have lots of new ABS files and stuff that I might want to locate.

2. Wouldn't run pacman-optimize before an update be more useful?

Nah, pacman-optimize defrags in effect, update will mess it up again.  Update, clean and defrag, sounds about right to me.

3. Do you always remove your packages with the -c option? Isn't this dangerous?

It would be it was anything other than orphans being removed, dependences of orphans can safely go on my system.

Thanks! smile

I have about 30 orphan programs, but I use pretty much all of them. One of the orphans was supertuxcart. o_0

Meskarune made me laugh. Shame on her, I'm supposed to be a tragic figure. O woe is me...

Methinks orphans can adopt themselves, no?

Re: Keeping arch system clean

I can also recommend "pacman -Rns $(pacman -Qdtq)". 

Once you've gotten rid of your orphans (or explicitly installed the ones you actually want) I would recommend this script that displays every package you've explicitly installed, excluding base and base-devel packages.  Very useful for finding packages you don't really want anymore.

pacman-explicit

#!/bin/bash
pacman -Qei | awk '/^Name/ { name=$3 } /^Groups/ { if ( $3 != "base" && $3 != "base-devel" ) { print name } }'

Oooh, I like that. I modified it slightly to save to a text document, but that's a very useful command. Saving to my ~/.scripts folder.

I also really like this. Very simple, very easy - the sort of thing that makes one say "why didn't I think of that?" I put it in a shell function rather than a separate script since it's so small.

Oh I like it too!!
Small modification so that I can also see the description.

pacman -Qei $(pacman -Qu|cut -d" " -f 1)|awk ' BEGIN {FS=":"}/^Name/{printf("\033[1;36m%s\033[1;37m", $2)}/^Description/{print $2}'

Modified because someone asked for it.

Re: Keeping arch system clean

I wrote pacgraph for a very similar purpose.  Basically it tells you how much space a "pacman -Rssc" would free up for any given package.  Use the --console switch for quickest results.

Re: Keeping arch system clean

Hadn't thought much about it but:

pacman -S $(pacman -Qqe | grep -vx "$(pacman -Qqm)")

will reinstall your explicits.  Sorry, it's late and need to go to bed big_smile.

That's the path to file that Meyithi used to create a backup of the database.

The script worked OK for you, nothing to worry about.
