pacman equivalent of "aptutude why"

Hi,
Is there a way to ask pacman why a package was autoinstalled? (i.e. as a dependency of which package)
Thanks,
Antony

The Pacman Rosetta on the wiki has the most comprehensive list of pacman's commands and their correlates in the other package manages.

You can use the query option with the info switch (-Qi) to print information about an installed package. See man pacman for the details.

If a package was installed as a dependency, you can run this command to see which packages require it:

pacman -Qi packagename | grep Required

It may not help if its required by multiple packages, but its a start.

pacman -Qii packagename

shows all installed packages depending on packagename.

I fail to see the benefits of '-Qii' over what the previous posters suggested. Backup Files don't matter much here.

C'mon, the wiki has only a couple thousand articles, shame on you if you haven't glanced them over already ;-)

You may also like a more general summary http://distrowatch.com/dwres.php?resour … management

There's also pactree (included with pacman), which will show recursive dependencies of a package.

This really ought to be mentioned somewhere. The only wiki article containing any reference is namcap, which I doubt non-dev users will read.
And I don't think most people will issue `pacman -Ql pacman` just to find the binary and other tools that the pacman package contains. Yes, most of them are more like dev-tools, but why shouldn't the users be aware of what great tools there are in the one of the most important package of the whole distro???

C'mon devs, at least mention it in the man pages of pacman or something.
[/rant]

Ok, what would be an appropriate way to document this on the wiki?
a)since makepkg is included in the package, I'd make a separate page for pactree
b) just mention it on the pacman wiki article

The whole http://www.archlinux.org/packages/commu … n-contrib/ package is cool, e.g. bacman deserves a mention too.

Oops, you're right. The way I remembered it, you needed to pass -i twice to see the Required By line, but that's obviously not correct.

Even if you make a separate page you'd need to link it in the pacman article or it'd not really serve a purpose.

There is also this:

expac -Q %N whateverpackageyouwanttocheck

Handy for scripts and such.

You were thinking about -Si and -Sii most likely.
