List of installed packages

[megadyptes]

Folks!

Is there a way to list the names of installed packages on a server install, and possible filter them by keyword similar to the way apt-cache can be used to look for packages in the repositories?

Try this :
dpkg --get-selections
then you can filter with grep.
dpkg --get-selections | grep -i keyword

Perfect!
