dpkg−query is a tool to show information about packages listed in the dpkg database.
−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 format.
−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 list alternatives.
−p |−−print−avail package-name
Display details about package-name, as found in /var/lib/dpkg/available.
−−licence | −−license
Display licence and copyright information.
−−version
Display version information.
−−admindir=dir
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 “$”.
Package information can be included by inserting variable references to package fields using the syntax “${field[;width]}”. Fields are printed right-aligned unless the width is negative in which case left alignment will be used. The following fields are recognised:
Architecture

Conffiles
Config−Version

Version
The default format string is “${Package}\t${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 −W −f=’${Package} ${Version}\t${Maintainer}\n’ dpkg
COLUMNS
This setting influences the output of the −−list option by changing the width of its output.
