How do I list all installed packages using rpm command on CentOS/Suse/Fedora/RHEL/Scientific and Red Hat Enterprise Linux?

The rpm command is a powerful Package Manager, which can be used to build, install, query, verify, update, and erase individual software packages. The latest version of Red hat and friends recommend using the yum command.
