Команды (Commands)
-x, --extract filename.dsc [output-directory]
              Extract a source package (--extract since dpkg 1.17.14).
              One non-option argument must be supplied, the name of the
              Debian source control file (.dsc).  An optional second
              non-option argument may be supplied to specify the
              directory to extract the source package to, this must not
              exist. If no output directory is specified, the source
              package is extracted into a directory named source-version
              under the current working directory.
              dpkg-source will read the names of the other file(s)
              making up the source package from the control file; they
              are assumed to be in the same directory as the .dsc.
              The files in the extracted package will have their
              permissions and ownerships set to those which would have
              been expected if the files and directories had simply been
              created - directories and executable files will be 0777
              and plain files will be 0666, both modified by the
              extractors' umask; if the parent directory is setgid then
              the extracted directories will be too, and all the files
              and directories will inherit its group ownership.
              If the source package uses a non-standard format
              (currently this means all formats except '1.0'), its name
              will be stored in debian/source/format so that the
              following builds of the source package use the same format
              by default.
       -b, --build directory [format-specific-parameters]
              Build a source package (--build since dpkg 1.17.14).  The
              first non-option argument is taken as the name of the
              directory containing the debianized source tree (i.e. with
              a debian sub-directory and maybe changes to the original
              files).  Depending on the source package format used to
              build the package, additional parameters might be
              accepted.
              dpkg-source will build the source package with the first
              format found in this ordered list: the format indicated
              with the --format command line option, the format
              indicated in debian/source/format, '1.0'.  The fallback to
              '1.0' is deprecated and will be removed at some point in
              the future, you should always document the desired source
              format in debian/source/format. See section SOURCE PACKAGE
              FORMATS for an extensive description of the various source
              package formats.
       --print-format directory
              Print the source format that would be used to build the
              source package if dpkg-source --build directory was called
              (in the same conditions and with the same parameters;
              since dpkg 1.15.5).
       --before-build directory
              Run the corresponding hook of the source package format
              (since dpkg 1.15.8).  This hook is called before any build
              of the package (dpkg-buildpackage calls it very early even
              before debian/rules clean). This command is idempotent and
              can be called multiple times. Not all source formats
              implement something in this hook, and those that do
              usually prepare the source tree for the build for example
              by ensuring that the Debian patches are applied.
       --after-build directory
              Run the corresponding hook of the source package format
              (since dpkg 1.15.8).  This hook is called after any build
              of the package (dpkg-buildpackage calls it last). This
              command is idempotent and can be called multiple times.
              Not all source formats implement something in this hook,
              and those that do usually use it to undo what
              --before-build has done.
       --commit [directory] ...
              Record changes in the source tree unpacked in directory
              (since dpkg 1.16.1).  This command can take supplementary
              parameters depending on the source format.  It will error
              out for formats where this operation doesn't mean
              anything.
       -?, --help
              Show the usage message and exit.  The format specific
              build and extract options can be shown by using the
              --format option.
       --version
              Show the version and exit.
