12.2. Using RPM
RPM has five basic modes of operation (not counting package building): installing, uninstalling, upgrading, querying, and verifying. This section contains an overview of each mode. For complete details and options, try
man rpm. You can also refer to Section 12.5, “Additional Resources” for more information on RPM.
12.2.1. Finding RPM Packages
Before using any RPM packages, you must know where to find them. An Internet search returns many RPM repositories, but if you are looking for RPM packages built by Red Hat, they can be found at the following locations:
- The Red Hat Enterprise Linux CD-ROMs
- The Red Hat Errata Page available at http://www.redhat.com/apps/support/errata/
- Red Hat Network — Refer to Chapter 15, Registering a System and Managing Subscriptions for more details on Red Hat Network.
