DESCRIPTION
       dpkg-query  is  a tool to show information about packages listed in the
       dpkg database.

COMMANDS
       -l | --list package-name-pattern ...
              List packages matching given pattern. If no package-name-pattern
              is  given,  list all packages in /var/lib/dpkg/status, excluding
              the ones marked with state purge.  Normal  shell  wildchars  are
              allowed  in  package-name-pattern. Please note you will probably
              have to quote package-name-pattern to  prevent  the  shell  from
              performing  filename  expansion.  For example this will list all
              package names starting with “libc6”:

                dpkg-query -l 'libc6*'

              The output format of this option is not configurable, but varies
              automatically  to  fit  the  terminal  width. It is intended for
              human readers,  and  is  not  easily  machine-readable.  See  -W
              (--show) and --showformat for a way to configure the output for‐
              mat.

       -W | --show package-name-pattern ...
              Just like the --list option this will list all packages matching
              the  given  pattern.  However the output can be customized using
              the --showformat option.  The default output  format  gives  one
              line  per  matching  package,  each  line  having  the  name and
              installed version of the package, separated by a tab.

       -s | --status package-name ...
              Report status of specified package. This just displays the entry
              in the installed package status database.

       -L | --listfiles package-name ...
              List files installed to your system from package-name.  However,
              note that files created by package-specific installation-scripts
              are not listed.

       -S | --search filename-search-pattern ...
              Search  for  a  filename  from  installed packages. All standard
              shell wildchars can be used in the pattern.  This  command  will
              not  list extra files created by maintainer scripts, nor will it
              Change  the  location of the dpkg database. The default location
              is /var/lib/dpkg.

       -f | --showformat=format
              This option is used to specify the format of the  output  --show
              will  produce.  The  format  is a string that will be output for
              each package listed.

              In the format string, “\” introduces escapes:

                  \n  newline
                  \r  carriage return
                  \t  tab

              “\” before any other character suppresses any special meaning of
              the following character, which is useful for “\” and “$”.

              Package information can be included by inserting variable refer‐
              ences to package fields  using  the  syntax  “${field[;width]}”.
              Fields are printed right-aligned unless the width is negative in
              which case left alignment will be used. The following fields are
              recognised:
