Deb is the Debian Linus installation format, very similar to Red Hat rpm, the most basic installation command is: dpkg-ifileThe . Deb Dpkg is a shorthand for the Debian package, a suite management system specifically developed for Debian, which facilitates the installation, updating and removal of software. All Linux distributions originating from Debian use dpkg, such as Ubuntu, Knoppix, and so on. Here are some common uses of Dpkg:1, Dpkg-i <package.deb>Install a Debian package, such as files you have manually downloaded. 2, Dpkg-c <package.deb>List<package.deb>the content. 3, Dpkg-i <package.deb>from<package.deb>To extract the package information. 4, Dpkg-r <package>Remove a package that has already been installed. 5, Dpkg-p <package>completely clears an installed package. Unlike remove, remove just deletes the data and executable files, and purge also removes all the configuration files. 6, Dpkg-l <package>List<package> List of all files installed. Please also see dpkg-c to check the contents of a. deb file. 7, Dpkg-s <package>displays information about the packages that have been installed. Also see apt-cache shows the package information in the Debian archive, as well as dpkg-I to display the package information extracted from a. deb file. 8, Dpkg-reconfigure <package>reconfigure an already installed package if it is using debconf (debconf provides a unified configuration interface for package installation).
