Hopefully short version of the question: If I'm on a machine that has a particular package installed, is there a yum command that will tell me which of it's configured repositories provided that package? (Or alternately, what repository would provide a yet-to-be-installed package.)

Background in case some context is needed: We have a maze of yum repositories that we draw from. I have a machine that has a particular rpm package installed, and another machine with an apparently insufficient maze of repositories configured, and so I am not able to install the package I want onto that machine. I need to add the minimal necessary repositories to the new machine. I can't just shotgun the repositories from one machine to the other. And just going out and grabbing the rpm isn't an option because I need this to be reproducible.

yum list packagename

That will show from which repository the package is in the third column of the output.

For already installed packages, that won't work, as the third column shows just "installed". In that case you can do e.g. "rpm -qi packagename", typically the Vendor, Packager and Build Host tags will give an indication to which repository the package belongs. Also it's quite common for some repo symbol being appended to the package version number.

repoquery -i {packagename} 

This will give you the actual repo name vs the unhelpful "installed" that yum returns. repoquery is provided by yum-utils.

You can use yum -v search that would show you packages along with repo it is present in. If you also add --showduplicates you will see all versions of that package.

For a single package, you can find this with

PACKAGE=ruby-enterprise
repoquery --qf "%{repoid}" $PACKAGE

Replace $PACKAGE with the name of the package you care about.

You can find all packages that came from a specific repository with

REPO=ruby-enterprise-opt
repoquery --repoid=$REPO -a --qf "%{name}" | sort > repo_packages
rpm -qa --qf "%{name}\n" | sort > installed_packages
comm -1 -2 repo_packages installed_packages

Replace $REPO with the id of the repository you care about; you can see the ids of all your enabled repositories with yum repolist.

Here are some ways of discovering the repository for a given installed package:

rpm -qi {packagename}

or

repoquery -i {packagename}

yum reinstall [package_name]

Then when asked to confirm, you can choose N to not change your system:

This should be equivalent to yum list installed, but with machine-readable output:

repoquery --installed '*' --queryformat='%{name} %{evr} %{ui_from_repo}' | column -t

Apparantly it's too much trouble to produce a man page listing the possible fields; but you can look through https://github.com/rpm-software-management/yum/blob/master/yum/packages.py and use whatever properties exist for the class of object you're listing.

e.g., if you're listing installed packages, you can use the fields of YumInstalledPackage, and hence the fields of its base classes YumHeaderPackage, YumAvailablePackage, PackageObject and RpmBase.

Here's an example:

$ repoquery --installed '*' --qf='%{name} %{evr} %{ui_from_repo}' | head -n 10 | column -t

It's worth reading the comment that documents the ui_from_repo property, in order to understand the possible format of this field.
