How to get installed/not installed state of **all** packages?

  • 772

I've found a bazillion references to get a list of the installed packages, but how can I print a single list of all known packages with their "package state" (not-installed, installed, half-installed etc. as defined by dpkg) in a shell, ideally like this:

awk   not-installed
bash  installed
cc    half-installed
[...]

dpkg --get-selections and dpkg --list only lists installed packages.

dpkg --get-selections '.' does not work.

apt-cache dump does not print whether packages are installed, and also prints a lot of irrelevant stuff.

I'm using Travis CI, which is running Ubuntu 12.04 LTS Server Edition 64 bit with for example dpkg-query 1.16.1.2.

    You want dpkg-query;

    For dpkg-query >= 1.17.11:

    dpkg-query -f '${Package}\t${db:Status-Status}\n' -W '*'

    For dpkg-query < 1.17.11:

    dpkg-query -f '${Package} ${Status}\n' -W '*' | awk '{print $1"\t"$4}'

    #1:

    • -f '${Package}\t${db:Status-Status}\n': When used with the -W option, specifies the format of the output (see man dpkg-query for other options);
    • -W '*': lists all the packages matching the pattern *;

    #2:

    • -f '${Package} ${Status}\n': When used with the -W option, specifies the format of the output (see man dpkg-query for other options);
    • -W '*': lists all the packages matching the pattern *;
    • awk '{print $1"\t"$4}': prints only the first and fourth field;

    In this case it seems like you want to list the status word, so I picked the db:Status-Status virtual field; here are the other virtual fields related to the package status:

                  db:Status-Abbrev
                     It contains the abbreviated package status, such as  "ii"
                     (since dpkg 1.16.2).

              db:Status-Want
                     It contains the package wanted status, part of the Status
                     field (since dpkg 1.17.11).

              db:Status-Status
                     It contains the package status word, part of  the  Status
                     field (since dpkg 1.17.11).

              db:Status-Eflag
                     It  contains  the  package status error flag, part of the
                     Status field (since dpkg 1.17.11).


    user@user-X550CL ~/tmp % dpkg-query -f '${Package}\t${db:status-status}\n' -W '*' | head
aalib1  not-installed
account-plugin-aim  installed
account-plugin-empathy  not-installed
account-plugin-facebook installed
account-plugin-flickr   installed
account-plugin-foursquare   not-installed
account-plugin-gadugadu not-installed
account-plugin-generic-oauth    not-installed
account-plugin-google   installed
account-plugin-groupwise    not-installed

  2. dpkg-query -l '*'

    will show you all the installed, uninstalled and half installed packages. Just grep on the package you want to filter.
