Which RPM package does a file belong to?

This trick is for systems such as Red Hat and Cent OS that use the RPM package management system.

So you have a file on your system but you want to figure out which package it belongs to.  The best way that I found to do this is the fowling

That command shows up what the name of the RPM is that is associated with the file /usr/libexec/fprintd

[user@server~]$ rpm -qf  /usr/libexec/fprintd

Now we can do a search to find the description of the package fprintd-pam.x86_64

[user@server~]$ yum search fprintd
Loaded plugins: refresh-packagekit, rhnplugin
*Note* Red Hat Network repositories are not listed below. You must run this command as root to access RHN repositories.

Name and summary matches only, use "search all" for everything.
