dpkg -l <package> You can use shell wildcards if you quote, e.g. dpkg -l 'dpkg-p*'. This gives (depending on your dpkg caches) something like Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Installed/Config-files/Unpacked/Failed-config/Half-installed |/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad) ||/ Name Version Description +++-==============-==============-============================================ ii dpkg-perl 0.1-3.0 Perl interface modules for dpkg pn dpkg-python <none> (no description available) from which you can easily see what is installed. In my case I want (column 1) and have (column 2) installed dpkg-perl. The perl-python package I want purged and is not installed. Very quick, very elegant.
