  • I sometimes want to know what packages are installed on my Ubuntu system. I still haven't figured out how to use aptitude effectively, so this is the next best thing. This allows finding by name. The grep '^ii' limits the display to only installed packages. If this is not specified, then it includes listing of non-installed packages as well. Show Sample Output


    1
    dpkg --list '*linux*' | grep '^ii'

  • The other commands were good, but they included packages that were installed and then removed. This command only shows packages that are currently installed, sorts smallest to largest, and formats the sizes to be human readable. Show Sample Output


    0
    dpkg-query --show --showformat='${Package;-50}\t${Installed-Size}\n' `aptitude --display-format '%p' search '?installed!?automatic'` | sort -k 2 -n | grep -v deinstall | awk '{printf "%.3f MB \t %s\n", $2/(1024), $1}'

  • Note: 1) Replace 'wonder' with any word you looking the meaning for in the above example 2) Need to install these packages: wordnet & wordnet-base (latter should be automatically installed because of dependency) 3) Combined size of packages is about 30MB on my old ubuntu system (I find it worth it) Show Sample Output
