Check RPM dependencies

In fact that's not a one but four different questions :).

*) First you can quickly list a downloaded package's dependencies/requirements by using the following commands:

$ rpm -qp mypackage.rpm --provides$ rpm -qp mypackage.rpm --requires

*) Second, you can use yum utility in order to satisfy these (somewhat cryptic) dependencies automatically (assuming that all your repositories are set up correctly, and all the dependencies are available):

$ sudo yum install mypackage.rpm

*) Third, there are several RPM search resources, some of them already suggested above. I'd like to list another one, just for the reference - pkgs.org.

*) Fourth, there is an additional popular repository for RHEL5 and RHEL6 distros - EPEL. Note that it's not supported by Red Hat.

Hope my answer(s) will help.

To merely list all dependencies of a package on the command-line, here is an example which builds upon the answer by Peter:

$ PKG="http://yum.postgresql.org/9.3/redhat/rhel-6.2-x86_64/pgdg-sl93-9.3-1.noarch.rpm"

Using yum (recommended):

$ yum -q deplist $PKGpackage: pgdg-sl93.noarch 9.3-1  dependency: sl-release   Unsatisfied dependency  dependency: /bin/sh   provider: bash.x86_64 4.1.2-8.el6  dependency: config(pgdg-sl93) = 9.3-1   provider: pgdg-sl93.noarch 9.3-1

-q above is of course optional and is equivalent to --quiet.

Using rpm:

$ rpm -qpR $PKG/bin/sh  config(pgdg-sl93) = 9.3-1rpmlib(CompressedFileNames) <= 3.0.4-1rpmlib(FileDigests) <= 4.6.0-1rpmlib(PayloadFilesHavePrefix) <= 4.0-1sl-release  

-qpR above is equivalent to --query --package --requires.

This site http://www.rpmfind.net/linux/RPM/ provides a search engine for rpm files. You can see dependencies and description. It also classifies them per distro.
