DPKG commands
There are two actions, they are dpkg-query
and dpkg-deb
.
Install a package
# sudo dpkg -i {package_name}
# sudo dpkg -i skype-ubuntu-precise_4.2.0.11-1_i386.deb
Remove a package
# sudo dpkg -r {package_name}
# sudo dpkg -r vlc
Remove a package and its configuration files
# sudo dpkg -P {package_name}
# sudo dpkg -P vlc
List all installed packages.
You can pipe the command to less
(a pager) so you can more easily scroll the content:
# dpkg -l | less
Check if the package is installed or not
# dpkg -l {package_name}
# dpkg -l vlc
Check if the package is installed or not, and if it is, launch it:
# dpkg -l | vlc
See whether a package is installed or not
And this will show the location where the package will be installed. Here -S
(capital S
) to search whether the package was installed or not.
# sudo dpkg -S {package_name}
# sudo dpkg -S skype
Install a *.deb package from a specified location
Here -R
is recursive. (Recursively handle all regular files matching the pattern *.deb
found at specified directories and all of its subdirectories).
# sudo dpkg -R --install {package_location}
# sudo dpkg -R --install /home/sysadmin/soft
Show package details
Here -p
(lowercase p
) will show the package info:
# dpkg -p {package_name}
# dpkg -p apache2
View the content of a package
Use -c
(lowercase c
) to show the content:
# sudo dpkg -c {package_name}
# sudo dpkg -c skype-ubuntu-precise_4.2.0.11-1_i386.deb
Extract the *.deb
package file
Use -x
(lowercase x
) to extract:
# dpkg -x {package_name} {location_were_to_extract}
# dpkg -x libqt4-phonon_4.6.3-4+squeeze1_i386.deb /home/sysadmin/
Extract and display the filenames contained in a package

# dpkg -X libqt4-phonon_4.6.3-4+squeeze1_i386.deb /home/sysadmin/
Display information about a package
Here -I
stands for information:
# dpkg -I {package_name}
# dpkg -I libqt4-phonon_4.6.3-4+squeeze1_i386.deb
Reconfigure an already installed package
dpkg-reconfigure
reconfigures packages after they already have been installed. Pass it the name(s) of a package or packages to reconfigure. It will ask configuration questions, much like when the package was first installed.
# dpkg-reconfigure postfix
This will reconfigure postfix
the same way as when you installed it for the first time.
