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

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.
