Some detailed

apt-Getinstall download and all dependent packages while installing or upgrading the package. If a package is set to hold (stop flag, it will be put aside (ie will not be upgraded). See below for more hold details. Apt-GetRemove [--Purge] Remove and any other parcels that depend on the package. --purge indicates that the package should be completely cleared (purged), for more information see dpkg-P. Apt-GetUpdate upgrades the package list from the Debian image, if you want to install any software on the day, run at least once a day, and each time you modify the/etc/apt/after sources.list, it must be executed. Apt-GetUpgrade [-U] Upgrade so the package that has been installed is the latest available version. New or removed old packages are not installed. If a package changes the dependency relationship and needs to install a new package, then it will not be upgraded, but is marked as hold. Apt-GetUpdate does not upgrade a package that is flagged as hold (this is the meaning of hold). See below how to manually set the package to hold. I recommend using both'- u'option, because then you can see which packages will be upgraded. Apt-GetDist-upgrade [-u] and apt-GetUpgrade similar, except dist-upgrade will install and remove packages to meet dependent relationships. Therefore, it has a certain danger. Apt-Cache Search searches for packages and descriptions that are met. Apt-the full description of the cache show. Apt-The cache showpkg shows many details, as well as relationships with other packages. 

Second, dpkg

A suite management system developed specifically for Debian to facilitate the installation, updating and removal of software. All "Linux" distributions originating from "Debian" use "dpkg", such as "Ubuntu", "Knoppix

Dpkg-------s displays information about the installed package. Also see apt-cache shows the package information in the Debian archive, and dpkg-I to display the package information extracted from a. deb file. Dpkg-reconfigure to reconfigure an already installed package if it is using debconf (debconf provides a unified configuration interface for package installation). You can re-formulate debconf it itself, as you want to change its front end or ask for priority. For example, to re-configure debconf, use a dialog front end, simple to run: dpkg-reconfigure--frontend=dialog debconf (if you chose the wrong installation, you can change it back yo:)
