following are some common usages of Dpkg:
1. dpkg -i <package.deb>
installs a Debian package, such as a file you downloaded manually.
2. dpkg -c <package.deb>
lists the contents of <package.deb>.
3. dpkg -I <package.deb>
extracts package information from <package.deb>.
4. dpkg -r
removes an installed package.
5. dpkg -P
completely removes an installed package. Unlike remove, remove only deletes data and executable files, while purge also deletes all configuration files.

7. dpkg -s
displays information about installed packages. Also see apt-cache to display package information in Debian archives, and dpkg -I to display package information extracted from a .deb file.

an installed package if it uses debconf (debconf provides a unified configuration interface for package installation).
