Ah, okay, thanks. We must've been in GMTA mode, at the same time. That's what I did, too.

Ok I need to write this down:
To get a list over everything that is installed on your arch system type the following command in a terminal:

Code: Select all

pacman -Qqe | grep -vx "$(pacman -Qqm)" > /path/to/chosen/directory/pkg.list

And when lightening strikes you can restore all of them like this;

Code: Select all

xargs -a /path/to/chosen/directory/pkg.list pacman -S --needed
.
Making it a cron job that runs just before the backup cron with our excellent backup script, gives you the home directory and the programs from the same time.

Removing groups of software by name-content

Postby viking60 » 02 Oct 2011, 15:32

I needed to remove anything containing gnome-shell on my laptop. If I do only

Code: Select all

sudo pacman -Rns gnome-shell
It will refuse to remove because of another package dependency and that package has dependencies again etc etc.

When I do a

Code: Select all

ls gnome-shell*
It lists packages starting with gnome shell but the * will not work in pacman.
This will do it though:

Code: Select all

sudo pacman -Rns $(pacman -Qq | grep gnome-shell)

This queries the database for anything containing "gnome-shell" (in this case) and removes it.

I always forget so I needed to write this down too :-D

Yes I constantly encourage people to write down some tips - How simple they might bee. The modesty and "everybody knows it" attitude is bad. I don't know everything that you might find to be elementary. So don't wait for the help cry Gurus!
I don't even know how to ask :confused

Also, thank you! The wiki has the first command wrong! I've been trying this for ages their way, to no avail!!!

To install with wildcard:

Code: Select all

pacman -S $(pacman -Ssq gnome-shell*)

This will install everything starting with gnome-shell with dependencies.
Just needed to write this down :-D

Man files to pdf

Postby viking60 » 02 Jun 2012, 11:32

I find it useful to save some man pages as pdf especially those about network and connetions.
This will write man netcfg to a pdf file:

Code: Select all

man -t netcfg -->netcfg.pdf


man -t will write the file in postscript format (via ps2pdf) that can be transfered to pdf.
if you do a

Code: Select all

man  netcfg -->netcfg.pdf
the pdf file will be created but there will be no content.

Re: Arch Linux tips 'n tricks - space problems

Postby viking60 » 04 Jul 2012, 12:28

When in space problems
Use ncdu -x / as root to see where space is taken.
Use pacman -Qdt to see orphan packages
Use bleachbit (AUR) to recover some
Use cacheclean (AUR) to limit # of old packages
Use pacgraph -c | less to
see which packages are largest disk users and ask yourself if you can do without them.
