Upgrading A Package From A Package File

If an updated version of a package has been downloaded from a non-repository source, it can be installed, replacing the previous version:

Table 14-8: Low-Level Package Upgrade Commands

Debian dpkg --install package_file

Red Hat rpm -U package_file

Example: Updating an existing installation of emacs to the version contained in the pack - age file emacs-22.1-7.fc7-i386.rpm on a Red Hat system:

rpm -U emacs-22.1-7.fc7-i386.rpm

Note: dpkg does not have a specific option for upgrading a package versus in- stalling one as rpm does.
