Dpkg is package manager for ubuntu/debian. It’s same as “rpm” is for redhat. Dpkg is used to build, install, remove and provide informations about ubuntu packages. dpkg itself is a low level tool which is used only to manage packages, instead of that APT is high level tool which could fetch the packages also from the remote locations and do some complex tasks. Then there comes tools like aptitude and synaptic which are having a more user friendly interface and a lot more complex ways of dealing with package management.

This is how you could use the dpkg:

  1. Install a package

    2. # dpkg -i <package name.deb>

  2. Install all packages recursively from a directory

    3. # dpkg -R <directory name>

  3. Remove a installed package expect configuration files

    4. # dpkg -r <package name-.deb>

  4. Remove a installed package with configuration files

    5. # dpkg -P <package name-.deb>

  5. Unpack the package but don’t configure it

    6. # dpkg –unpack <package_file-.deb>

  6. Reconfigure an unpacked package

    7. # dpkg –configure <package file-.deb>

  7. Forget about uninstalled available packages

    8. # dpkg –forget-old-unavail

  8. Erase the existing information about what packages are available.

    9. # dpkg –clear-avail

  9. Searches for packages that have been installed only partially on your system.

    10. # dpkg -C

  10. Compare Package version numbers

    11. # dpkg –compare-versions <package 2> op <package 1>
