then the command:

dpkg  i  R /usr/local/Debian/archive

will direct dpkg to install all the packages found there. dpkg will install the

packages in the order it finds them. This leaves open the possibility that

dependencies will not be satisfied during the first pass. On large complex

collections of packages this can potentially take several passes at the package

files.

A more general solution is to break the installation phase into two steps.

The first step unpacks the package file, while the second step configures the

unpacked files. Just which files are unpacked, and where they are placed after

unpacking, is determined by a collaboration between dpkg and the package.

  unpack 

Sometimes, as when dependencies get in the way of installation, it is desirable

to break the installation into two separate steps. The   unpack option performs

the first step of the installation. dpkg extracts files from the package and places

them in their correct locations in the file system.

The configuration of the package, including the installation of configuration

files, known as conffiles, is postponed until a later time.

Like install, this option will accept the  R |   recursive option. This allows for

unpacking all of the packages in the given directory tree. Following up on the

example discussed for   install, a large collection of packages gets unpacked by

a command like the following:

dpkg   unpack /usr/local/Debian/archive
