Ubuntu - list packages installed on ubuntu system

listing installed packages on an ubuntu system is simple - just drop into a terminal and type the following:

dpkg --get-selections | grep -v deinstall

then you can use grep to find the package you're looking for, so for example - to find 'gaim' (and related packages), just do:

$ dpkg --get-selections | grep -v deinstall| grep gaim
gaim install
gaim-data install
$
