Using dpkg-query also has the advantage that you can specify the output format: 0 17:34 0 claudius@ares: ~/Desktop $ dpkg-query --load-avail -f '${binary:Summary}\n' -W pidgin2 No packages found matching pidgin2. 1 17:34 0 claudius@ares: ~/Desktop $ dpkg-query --load-avail -f '${binary:Summary}\n' -W jarwrapper (no description available) 0 17:34 0 claudius@ares: ~/Desktop $ dpkg-query --load-avail -f '${binary:Summary}\n' -W pidgin graphical multi-protocol instant messaging client for X 0 17:34 0 claudius@ares: ~/Desktop $ dpkg-query -f '${binary:Summary}\n' -W jarwrapper No packages found matching jarwrapper. 1 17:35 0 claudius@ares: ~/Desktop $ Note the return code of 1 when no packages are found.
