The command we need to use to list the packages currently installed in Ubuntu or Debian is dpkg –get-selections. For example:

# dpkg --get-selections
acpi                                            install
acpi-support-base                               install
acpid                                           install
adduser                                         install
apache2                                         install

bash                                            install
bind9-host                                      install
binutils                                        install

It will return a long list showing all the installed packages. To filter to specific list of packages, for example we only need to show java packages, combine it with grep, for example:

# dpkg --get-selections|grep java
java-common                                     install
java-gcj-compat                                 install
java-gcj-compat-headless                        install
libbcel-java                                    install
liblog4j1.2-java                                install
liblog4j1.2-java-gcj                            install
libmx4j-java                                    install
libpg-java                                      install
libregexp-java                                  install
sun-java6-bin                                   install
sun-java6-jdk                                   install
sun-java6-jre                                   install

We can find the locations of the files within a package from the list by using the dpkg -L command, such as:

# dpkg -L sun-java6-jdk|more
