pacman - short question about usage

Hi,

while searching the database with "pacman -Ss foobar", is it possible to show which of the resulting package names are already installed? In Debian it's shown via "aptitude search foobar", but I can't find the corresponding option for pacman in its man page.

Thanks for your answer.

Re: pacman - short question about usage

Try ....pacman -Q |less.....

Shows all pkgs installed in your system.....

Re: pacman - short question about usage

Yes, I already stumbled upon that. But it would be nice to be able to see, when searching for a packet, that a similar one is already installed.

Re: pacman - short question about usage

Pacman -S (pkg name)....will give a response indicating it is already installed if it is indeed in your system.

Re: pacman - short question about usage

Yaourt will do this. The output from yaourt -Ss packagename will show the list of available packages and will highlight the ones already installed sort of like this:

yaourt -Ss foo
/current
foo 1.0 [installed]
foo-cvs
foo-fake

Yaourt is available in the archlinuxfr respository. See this thread for info: http://bbs.archlinux.org/viewtopic.php?id=25718

It has the added benefit of searching and installing packages from the AUR too.

Re: pacman - short question about usage

the best command for packages info is:

$psearch -ac pkgname

(don't forget "man psearch"...).
Get it from AUR and you'll enjoy a new life!
for "global picture" of packages - jacman (just a bit slow...).

Re: pacman - short question about usage

Yaourt looks exactly like the way I wanted pacman :-) I will also try psearch, installing with yaourt from AUR :]

Thanks!!

Re: pacman - short question about usage

yaourt was noticably slower than psearch when I tried. And somehow I didn't like yaourt building management. (For building I use my own bash script which works in most cases. But that just taste.)
But the main thing - I couldn't find in yaourt the elegant compact analogue output as $psearch -ac keyword
Can anyone tell?

Re: pacman - short question about usage

As I said,

$psearch gimp [b]!=[/b] $psearch -ac gimp

-a - includes searches from AUR
-c - gives you a compact view which you never forget in your life!!!
use

$psearch -ac gnome games

should give logical AND.
Yes... OR should?... because at this moment of writing, after upgrading from AUR, psearch started giving errors...  It looks like I will need to write something like psearch for myself, too...

Re: pacman - short question about usage

i installed psearch, but I just gave an error message and listed the repository names.... do I have to configure it somewhere or is that the error you mentioned, aris?

Re: pacman - short question about usage

Yes, this is the error. Let's try to investigate. Someone might have already found this on forums or in AUR comments...

Re: pacman - short question about usage

thanks to a clever man grizz ,  I can confirm that psearch (0.8.3 - see post above) is working once again. Let's hope someone will repair the one in the AUR, too.
So, Kei and others , if you don't have your own repo, it's time to start one:

1. Create a dir e.g #mkdir /home/keipkgs
2. #cd /home/keipkgs
3. #wget http://grizz.pl/PKG/psearch-0.8-3-i686.pkg.tar.gz
4. as root edit /etc/pacman.conf - add above all servers 2 lines like:
[keipkgs]
Server = file:///home/keipkgs
5. pacman -S psearch

Enjoy psearch!

Re: pacman - short question about usage

Thanks! But I'm a little bit confused about the local repository. When I follow your instructions, I get an error that no 'myLocalRepo.db.tar.gz' file is present. That's right, but how do I get this file? I looked in the wiki, where it says, that the new script repo-add should be used, but this script also need the *db.tar.gz file to be present. How do I generate it?

Use 'gensync'. There's a wiki page about it.

Re: pacman - short question about usage

Sorry, I've forgot to mention - but I think "repo-add" is more elegant solution. Personaly, I use a script which I call "auri" based on "aur-install", too. It also builds packages.

If anyone likes it you can improve
