There are many different kinds of Linux package files. Most of these are associated with the package managers of specific Linux distributions. Examples are Debian Package files ( .deb files), RPM Package Manager files ( .rpm files), Tarballs ( .tar files) and .run files. This section deals with installing these single files.
