NAME

       dpkg-query - a tool to query the dpkg database

SYNOPSIS

       dpkg-query [option...] command

DESCRIPTION

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

COMMANDS

       -l, --list [package-name-pattern...]
           List all known packages matching one or more patterns, regardless of their status, which includes any
           real or virtual package referenced in any dependency relationship field (such as Breaks, Enhances,
           etc.).  If no package-name-pattern is given, list all packages in /var/lib/dpkg/status, excluding the
           ones marked as not-installed (i.e.  those which have been previously purged).  Normal shell wildcard
           characters 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 first three columns of the output show the desired action, the package status, and errors, in
           that order.

           Desired action:

           u = Unknown
           i = Install
           h = Hold
           r = Remove
           p = Purge

           Package status:

           n = Not-installed
           c = Config-files
           H = Half-installed
           U = Unpacked
           F = Half-configured
           W = Triggers-awaiting
           t = Triggers-pending
           i = Installed

           Error flags:

           <empty> = (none)
           R = Reinst-required

           An uppercase status or error letter indicates the package is likely to cause severe problems. Please
           refer to dpkg(1) for information about the above states and flags.

           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 format.

       -W, --show [package-name-pattern...]
           Just like the --list option this will list all packages matching the given patterns. 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 (extended with the architecture qualifier for Multi-Arch
           same packages) and installed version of the package, separated by a tab.

       -s, --status [package-name...]
           Report status of specified packages. This just displays the entry in the installed package status
           database.  If no package-name is specified it will display all package entries in the status database
           (since dpkg 1.19.1).  When multiple package-name entries are listed, the requested status entries are
           separated by an empty line, with the same order as specified on the argument list.

       -L, --listfiles package-name...
           List files installed to your system from package-name. When multiple package-names are listed, the
           requested lists of files are separated by an empty line, with the same order as specified on the
           argument list.

           Each file diversion is printed on its own line after its diverted file, prefixed with one of the
           following localized strings:

             locally diverted to: diverted-to
             package diverts others to: diverted-to
             diverted by pkg to: diverted-to

           Hint: When machine parsing the output, it is customary to set the locale to C.UTF-8 to get
           reproducible results.

           This command will not list extra files created by maintainer scripts, nor will it list alternatives.

       --control-list package-name
           List control files installed to your system from package-name (since dpkg 1.16.5).  These can be used
           as input arguments to --control-show.

       --control-show package-name control-file
           Print the control-file installed to your system from package-name to the standard output (since dpkg
           1.16.5).

       -c, --control-path package-name [control-file]
           List paths for control files installed to your system from package-name (since dpkg 1.15.4).  If
           control-file is specified then only list the path for that control file if it is present.

           Warning: this command is deprecated as it gives direct access to the internal dpkg database, please
           switch to use --control-list and --control-show instead for all cases where those commands might give
           the same end result. Although, as long as there is still at least one case where this command is
           needed (i.e. when having to remove a damaging postrm maintainer script), and while there is no good
           solution for that, this command will not get removed.

       -S, --search filename-search-pattern...
           Search for packages that own files corresponding to the given patterns.  Standard shell wildcard
           characters can be used in the pattern, where asterisk (*) and question mark (?) will match a slash,
           and backslash (\) will be used as an escape character.

           If the first character in the filename-search-pattern is none of ‘*[?/’ then it will be considered a
           substring match and will be implicitly surrounded by ‘*’ (as in *filename-search-pattern*).  If the
           subsequent string contains any of ‘*[?\’, then it will handled like a glob pattern, otherwise any
           trailing ‘/’ or ‘/.’ will be removed and a literal path lookup will be performed.

           This command will not list extra files created by maintainer scripts, nor will it list alternatives.

           The output format consists of one line per matching pattern, with a list of packages owning the
           pathname separated by a comma (U+002C ‘,’) and a space (U+0020 ‘ ’), followed by a colon (U+003A ‘:’)
           and a space, followed by the pathname. As in:

             pkgname1, pkgname2: pathname1
             pkgname3: pathname2

           File diversions are printed with the following localized strings:

             diversion by pkgname from: diverted-from
             diversion by pkgname to: diverted-to

           or for local diversions:

             local diversion from: diverted-from
             local diversion to: diverted-to

           Hint: When machine parsing the output, it is customary to set the locale to C.UTF-8 to get
           reproducible results.

       -p, --print-avail [package-name...]
           Display details about packages, as found in /var/lib/dpkg/available.  If no package-name is
           specified, it will display all package entries in the available database (since dpkg 1.19.1).  When
           multiple package-name are listed, the requested available entries are separated by an empty line,
           with the same order as specified on the argument list.

           Users of APT-based frontends should use apt show package-name instead as the available file is only
           kept up-to-date when using dselect.

       -?, --help
           Show the usage message and exit.

       --version
           Show the version and exit.

OPTIONS

       --admindir=dir
           Change the location of the dpkg database. The default location is /var/lib/dpkg.

       --root=directory
           Set the root directory to directory, which sets the administrative directory to
           «directory/var/lib/dpkg» (since dpkg 1.21.0).

       --load-avail
           Also load the available file when using the --show and --list commands, which now default to only
           querying the status file (since dpkg 1.16.2).

       --no-pager
           Disables the use of any pager when showing information (since dpkg 1.19.2).

       -f, --showformat=format
           This option is used to specify the format of the output --show will produce (short option since dpkg
           1.13.1).  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 references 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 recognized but they are not necessarily
           available in the status file (only internal fields or fields stored in the binary package end up in
           it):

           Version

           The following are virtual fields, generated by dpkg-query from values from other fields (note that
           these do not use valid names for fields in control files):

           binary:Package
               It contains the binary package name with a possible architecture qualifier like “libc6:amd64”
               (since dpkg 1.16.2).  An architecture qualifier will be present to make the package name
               unambiguous, for example if the package has a Multi-Arch field with a value of same or the
               package is of a foreign architecture.

           binary:Synopsis
               It contains the package short description (since dpkg 1.19.1).

           binary:Summary
               This is an alias for binary:Synopsis (since dpkg 1.16.2).

           db:Status-Abbrev
               It contains the abbreviated package status (as three characters), such as “ii ” or “iHR” (since
               dpkg 1.16.2).  See the --list command description for more details.

           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).

           db-fsys:Files
               It contains the list of the package filesystem entries separated by newlines (since dpkg 1.19.3).

           db-fsys:Last-Modified
               It contains the timestamp in seconds of the last time the package filesystem entries were
               modified (since dpkg 1.19.3).

           source:Package
               It contains the source package name for this binary package (since dpkg 1.16.2).

           source:Version
               It contains the source package version for this binary package (since dpkg 1.16.2)

           source:Upstream-Version
               It contains the source package upstream version for this binary package (since dpkg 1.18.16)

           The default format string is “${binary:Package}\t${Version}\n”.  Actually, all other fields found in
           the status file (i.e. user defined fields) can be requested, too. They will be printed as-is, though,
           no conversion nor error checking is done on them. To get the name of the dpkg maintainer and the
           installed version, you could run:

            dpkg-query -f='${binary:Package} ${Version}\t${Maintainer}\n' \
             -W dpkg

EXIT STATUS

       0   The requested query was successfully performed.

       1   The requested query failed either fully or partially, due to no file or package being found (except
           for --control-path, --control-list and --control-show were such errors are fatal).

       2   Fatal or unrecoverable error due to invalid command-line usage, or interactions with the system, such
           as accesses to the database, memory allocations, etc.

ENVIRONMENT

   External environment
       SHELL
           Sets the program to execute when spawning a command via a shell (since dpkg 1.19.2).

       PAGER
       DPKG_PAGER
           Sets the pager command to use (since dpkg 1.19.1), which will be executed with «$SHELL -c».  If SHELL
           is not set, «sh» will be used instead.  The DPKG_PAGER overrides the PAGER environment variable
           (since dpkg 1.19.2).

       DPKG_ROOT
           If set and the --root option has not been specified, it will be used as the filesystem root directory
           (since dpkg 1.21.0).

       DPKG_ADMINDIR
           If set and the --admindir option has not been specified, it will be used as the dpkg data directory.

       DPKG_COLORS
           Sets the color mode (since dpkg 1.18.5).  The currently accepted values are: auto (default), always
           and never.

   Internal environment
       LESS
           Defined by dpkg-query to “-FRSXMQ”, if not already set, when spawning a pager (since dpkg 1.19.2).
           To change the default behavior, this variable can be preset to some other value including an empty
           string, or the PAGER or DPKG_PAGER variables can be set to disable specific options with «-+», for
           example DPKG_PAGER="less -+F".
