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.
