Removing packages from linux (ubuntu)

I tried to remove the packages from maverick (Ubuntu 10.10), today..and found some good ways to do it

(A)First search the package :

The traditional way:

dpkg -l | grep partial-name-of-package-to-be-removed

Using dpkg command ....more conspicuous way

dpkg -l '*partial-name-of-package-to-be-removed*'

For example, you want to remove jdk then

dpkg -l '*jdk*'

(B)There are two ways to remove packages:

Using apt command : ...the better way...

After getting the list of packages choose the appropriate one and run following command

* To remove packages:

sudo apt-get remove package-name

* To remove packages and dependencies:

sudo apt-get autoremove package-name

* To remove packages, dependencies and configuration files:

sudo apt-get purge package-name

Using dpkg command : ...the crude way...

* To remove packages:

sudo dpkg -r package-name

* To remove packages,and configuration files:

sudo dpkg --purge package-name

* To force removal, if got dependency error(this command turns errors into warning..):

sudo dpkg --purge --force-depends package-name
