2.2.3 Naming conventions for Debian package filenames

The Debian package filenames conform to the following convention:

     foo_ver-rev_arch.deb

where, usually, foo is the package name, ver is the upstream version number, rev is the Debian revision number, and arch is the target architecture. Files are easily renamed, of course. You can find out what package is really contained in any given file of name filename by running the following command:

     dpkg --info filename

The Debian revision number is specified by the Debian developer or by whoever built the package. A change in revision number usually indicates that some aspect of the packaging has changed.
