dpkg-source [option...] command

       dpkg-source packs and unpacks Debian source archives.

       None  of these commands allow multiple options to be combined into one,
       and they do not allow the value for an option to be specified in a sep-
       arate argument.

       -x filename.dsc [output-directory]
              Extract  a  source package. One non-option argument must be sup-
              plied, 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 directory [format-specific-parameters]
              Build a source package. 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 --for-
              mat   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/for-
              mat.  See  section  SOURCE  PACKAGE  FORMATS  for  an  extensive
              description of the various source package formats.
              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. 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.  This
              command  can  take  supplementary  parameters  depending  on the
              source format.  It will error out for formats where this  opera-
              tion doesn't mean anything.

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

              Show the version and exit.

              Specifies the main source control file to read information from.
              The default is debian/control.  If given with relative  pathname
              this  is  interpreted  starting  at  the source tree's top level

              Specifies the change log file  to  read  information  from.  The
              default  is  debian/changelog.   If given with relative pathname
              this is interpreted starting at  the  source  tree's  top  level

              Specifies  the format of the changelog. By default the format is
              read from a special line near the bottom  of  the  changelog  or
              failing that defaults to the debian standard format.

              Use  the  given  format for building the source package. It does
              override any format given in debian/source/format.

              Set an output substitution variable.  See deb-substvars(5) for a
              discussion of output substitution.

              Specify  the  compression to use for created files (tarballs and
              diffs).  Note that this option will not cause existing  tarballs
              to  be recompressed, it only affects new files. Supported values
              are: gzip, bzip2, lzma and xz.  gzip is the default. xz is  only
              supported since dpkg-dev 1.15.5.

       -zlevel, --compression-level=level
              Compression  level to use. As with -Z it only affects newly cre-
              ated files. Supported values are: 1 to 9, best, and  fast.   The
              default is 9 for gzip and bzip2, 6 for xz and lzma.

       -i[regexp], --diff-ignore[=regexp]
              You  may  specify  a  perl regular expression to match files you
              want filtered out of the list of files for the diff. (This  list
              is generated by a find command.) (If the source package is being
              built as a version 3 source package using a  VCS,  this  can  be
              used  to ignore uncommited changes on specific files. Using -i.*
              will ignore all of them.)  -i by itself enables the option, with
              a default regexp that will filter out control files and directo-
              ries of the most common revision  control  systems,  backup  and
              swap  files and Libtool build output directories. There can only
              be one active regexp, of multiple -i options only the  last  one
              will take effect.

              This  is  very  helpful in cutting out extraneous files that get
              included in the diff, e.g. if you  maintain  your  source  in  a
              revision  control  system  and want to use a checkout to build a
              source package without including the additional files and direc-
              tories  that  it  will  usually  contain (e.g. CVS/, .cvsignore,
              .svn/). The default regexp is already very  exhaustive,  but  if
              you need to replace it, please note that by default it can match
              any part of a path, so if you want to match the begin of a file-
              name or only full filenames, you will need to provide the neces-
              sary anchors (e.g. '(^|/)', '($|/)') yourself.

              The perl regular expression specified will  extend  the  default
              value  of  --diff-ignore and its current value (if set). It does
              this by concatenating "|regexp" to  the  existing  value.   This
              option  is convenient to use in debian/source/options to exclude
              some auto-generated files from the automatic patch generation.

       -I[file-pattern], --tar-ignore[=file-pattern]
              If this option is specified,  the  pattern  will  be  passed  to
              tar(1)'s  --exclude  option  when  it  is  called  to generate a
              .orig.tar or .tar file. For example, -ICVS will  make  tar  skip
              over  CVS directories when generating a .tar.gz file. The option
              may be repeated multiple times  to  list  multiple  patterns  to

              -I by itself adds default --exclude options that will filter out
              control files and directories of the most common  revision  con-
              trol  systems,  backup  and  swap files and Libtool build output

       output of the --help command.

              Do not copy original tarballs near the extracted source package.

              Do not check signatures and checksums before unpacking.

              Refuse  to  unpack  the  source package if it doesn't contain an
              OpenPGP signature that can be verified either  with  the  user's
              trustedkeys.gpg keyring, one of the vendor-specific keyrings, or
              one      of       the       official       Debian       keyrings
              (/usr/share/keyrings/debian-keyring.gpg                      and

       If you don't know what source format to use, you should  probably  pick
       either      "3.0      (quilt)"      or      "3.0     (native)".     See
       http://wiki.debian.org/Projects/DebSrc3.0  for   information   on   the
       deployment of those formats within Debian.

   Format: 1.0
       A source package in this format consists either of a .orig.tar.gz asso-
       ciated to a .diff.gz or a single .tar.gz (in that case the  package  is
       said to be native).


       Extracting  a  native package is a simple extraction of the single tar-
       ball in the target directory. Extracting a non-native package  is  done
       by  first  unpacking  the .orig.tar.gz and then applying the patch con-
       tained in the .diff.gz file. The timestamp  of  all  patched  files  is
       reset  to  the extraction time of the source package (this avoids time-
       stamp skews leading to problems when autogenerated files are  patched).
       The  diff  can  create new files (the whole debian directory is created
       that way) but can't remove files (empty files will be left over).


       Building a native package is just creating a single  tarball  with  the
       source directory. Building a non-native package involves extracting the
       original tarball in a separate ".orig" directory and  regenerating  the
       .diff.gz  by  comparing  the  source  package  directory with the .orig

       Build options (with -b):

       If a second non-option argument is supplied it should be  the  name  of
       the  original  source  directory  or tarfile or the empty string if the
              directory if  it  isn't  already  there.  The  tarball  will  be
              unpacked into directory.orig for the generation of the diff.

       -sp    Like -sk but will remove the directory again afterwards.

       -su    Specifies  that  the original source is expected as a directory,
              by default package-upstream-version.orig  and  dpkg-source  will
              create a new original source archive from it.

       -sr    Like -su but will remove that directory after it has been used.

       -ss    Specifies that the original source is available both as a direc-
              tory and as a tarfile. dpkg-source will  use  the  directory  to
              create  the  diff,  but  the  tarfile  to create the .dsc.  This
              option must be used with care - if the directory and tarfile  do
              not match a bad source archive will be generated.

       -sn    Specifies to not look for any original source, and to not gener-
              ate a diff.  The second argument, if supplied, must be the empty
              string.  This  is used for Debian-specific packages which do not
              have a separate upstream source and therefore have no debianisa-
              tion diffs.

       -sa or -sA
              Specifies  to  look for the original source archive as a tarfile
              or as a directory - the second argument, if any, may be  either,
              or  the  empty  string  (this is equivalent to using -sn).  If a
              tarfile is found it will unpack it to create the diff and remove
              it  afterwards  (this  is  equivalent to -sp); if a directory is
              found it will pack it to create the original source  and  remove
              it  afterwards  (this is equivalent to -sr); if neither is found
              it will assume that the package has no debianisation diffs, only
              a  straightforward  source  archive (this is equivalent to -sn).
              If both are found then dpkg-source will  ignore  the  directory,
              overwriting it, if -sA was specified (this is equivalent to -sP)
              or raise an error if -sa was specified.  -sA is the default.

              The process fails if the  generated  diff  contains  changes  to
              files  outside  of  the debian sub-directory. This option is not
              allowed  in   debian/source/options   but   can   be   used   in

       Extract options (with -x):

       In all cases any existing original source tree will be removed.

       -sp    Used  when  extracting then the original source (if any) will be
              left as a tarfile. If it is not already located in  the  current
              directory  or if an existing but different file is there it will
              be copied there.  (This is the default).

       -su    Unpacks the original source tree.

   Format: 2.0
       Also known as wig&pen. This format is not recommended  for  wide-spread
       usage,  the  format  "3.0  (quilt)"  replaces it. Wig&pen was the first
       specification of a new-generation source package format.

       The behaviour of this format is the same as the  "3.0  (quilt)"  format
       except  that  it  doesn't use an explicit list of patches. All files in
       debian/patches/ matching the perl regular  expression  [\w-]+  must  be
       valid patches: they are applied at extraction time.

       When  building  a new source package, any change to the upstream source
       is stored in a patch named zz_debian-diff-auto.

   Format: 3.0 (native)
       This format is an extension of the native package format as defined  in
       the  1.0 format. It supports all compression methods and will ignore by
       default any VCS specific files and directories as well as  many  tempo-
       rary  files  (see  default  value associated to -I option in the --help

   Format: 3.0 (quilt)
       A source package in this format contains at least an  original  tarball
       (.orig.tar.ext where ext can be gz, bz2, lzma and xz) and a debian tar-
       ball (.debian.tar.ext). It can also contain  additional  original  tar-
       balls  (.orig-component.tar.ext).   component can only contain alphanu-
       meric characters and dashes ("-").


       The main original tarball is extracted first, then all additional orig-
       inal tarballs are extracted in subdirectories named after the component
       part of their filename (any pre-existing directory  is  replaced).  The
       debian  tarball is extracted on top of the source directory after prior
       removal of any pre-existing debian directory. Note that the debian tar-
       ball must contain a debian sub-directory but it can also contain binary
       files outside of that directory (see --include-binaries option).

       All    patches    listed     in     debian/patches/debian.series     or
       debian/patches/series are then applied.  If the former file is used and
       the latter one doesn't exist (or is a  symlink),  then  the  latter  is
       replaced  with a symlink to the former. This is meant to simplify usage
       of quilt to  manage  the  set  of  patches.  Note  however  that  while
       dpkg-source  parses  correctly  series files with explicit options used
       for patch application (stored on each line after the patch filename and
       one  or  more  spaces),  it does ignore those options and always expect
       patches that can be applied with the -p1 option of patch. It will  thus
       emit a warning when it encounters such options, and the build is likely
       to fail.

       Similarly to quilt's default behaviour, the patches  can  remove  files

       The  file  .pc/applied-patches  is  created  if  some patches have been
       applied during the extraction.
       added/removed from the series file and from the quilt metadata.

       Any  change  on  a  binary file is not representable in a diff and will
       thus lead to a failure unless the maintainer  deliberately  decided  to
       include  that modified binary file in the debian tarball (by listing it
       in debian/source/include-binaries). The build  will  also  fail  if  it
       finds  binary  files  in the debian sub-directory unless they have been
       whitelisted through debian/source/include-binaries.

       The updated debian directory and the list of modified binaries is  then
       used to generate the debian tarball.

       The  automatically  generated  diff doesn't include changes on VCS spe-
       cific files as well as many temporary files (see default value  associ-
       ated  to -i option in the --help output). In particular, the .pc direc-
       tory used by quilt is ignored during generation of the automatic patch.

       Note: dpkg-source --before-build (and -b) will ensure that all  patches
       listed  in  the  series file are applied so that a package build always
       has all patches applied. It does  this  by  finding  unapplied  patches
       (they  are  listed  in the series file but not in .pc/applied-patches),
       and if the first patch in that set can be applied  without  errors,  it
       will apply them all. The option --no-preparation can be used to disable
       this behavior.

       Recording changes

       --commit [directory] [patch-name] [patch-file]
              Generates a patch corresponding to the local  changes  that  are
              not  managed  by the quilt patch system and integrates it in the
              patch system under the name patch-name. If the name is  missing,
              it  will  be  asked interactively. If patch-file is given, it is
              used as the patch corresponding to the local  changes  to  inte-
              grate. This is mainly useful after a build failure that pre-gen-
              erated this file. Once integrated, an editor is launched so that
              you can edit the meta-information in the patch header.

       Build options

              Allow  dpkg-source to build the source package if the version of
              the quilt metadata is the one  specified,  even  if  dpkg-source
              doesn't know about it. Effectively this says that the given ver-
              sion of the quilt metadata is compatible with the version 2 that
              dpkg-source  currently  supports. The version of the quilt meta-
              data is stored in .pc/.version.

              Do not ignore removed files and include them  in  the  automati-
              cally generated patch.

              Use       debian/patches/debian-changes        instead        of
              debian/patches/debian-changes-version  for the name of the auto-
              matic patch generated during build. This option is  particularly
              useful  when  the package is maintained in a VCS and a patch set
              can't reliably be  generated.  Instead  the  current  diff  with
              upstream should be stored in a single patch. The option would be
              put in debian/source/local-options and would be accompanied by a
              debian/source/local-patch-header  file explaining how the Debian
              changes can be best reviewed, for example in  the  VCS  that  is

              Automatically  create the main original tarball as empty if it's
              missing and if there are supplementary original  tarballs.  This
              option  is  meant  to  be used when the source package is just a
              bundle of multiple upstream software and where there's no "main"

              Unapply the patches in the --after-build hook. You usually don't
              need this option as dpkg-source will automatically  unapply  the
              patches  if it did apply them during --before-build. This option
              is only allowed in debian/source/local-options so that all  gen-
              erated source packages have the same behavior by default.

              The process fails if an automatic patch has been generated. This
              option can be used to ensure  that  all  changes  were  properly
              recorded  in  separate quilt patches prior to the source package
              build. This option is not allowed in  debian/source/options  but
              can be used in debian/source/local-options.

              The  process  doesn't fail if an automatic patch has been gener-
              ated, instead it's immediately recorded in the quilt series.

       Extract options

              Skips extraction of the debian tarball on top  of  the  upstream

              Do not apply patches at the end of the extraction.

   Format: 3.0 (custom)
       This format is special. It doesn't represent a real source package for-
       mat but can be used to create source packages with arbitrary files.

       Build options

       All non-option arguments are taken as files to integrate in the  gener-
       ated  source package. They must exist and are preferably in the current
       .gitshallow file listing revisions for a shallow git clone.


       The bundle is cloned as a git repository to the target  directory.   If
       there  is  a  gitshallow file, it is installed as `.git/shallow` inside
       the cloned git repository.

       Note that by default the new  repository  will  have  the  same  branch
       checked  out  that  was  checked out in the original source. (Typically
       "master", but it could be anything.) Any other branches will be  avail-
       able under `remotes/origin/`.


       Before  going any further, some checks are done to ensure that we don't
       have any non-ignored uncommitted changes.

       git-bundle(1) is used to generate a bundle of the git  repository.   By
       default,  all  branches  and tags in the repository are included in the

       Build options

              Allows specifying a git ref to include in the  git  bundle.  Use
              disables  the  default  behavior  of  including all branches and
              tags. May be specified multiple times. The ref can be  the  name
              of a branch or tag to include. It may also be any parameter that
              can be passed to git-rev-list(1). For example, to  include  only
              the master branch, use --git-ref=master. To include all tags and
              branches, except for the  private  branch,  use  --git-ref=--all

              Creates  a  shallow clone with a history truncated to the speci-
              fied number of revisions.

   Format: 3.0 (bzr)
       This format is experimental. It generates a single  tarball  containing
       the bzr repository.


       The  tarball  is  unpacked and then bzr is used to checkout the current


       Before going any further, some checks are done to ensure that we  don't
       have any non-ignored uncommitted changes.

       Then  the VCS specific part of the source directory is copied over to a
       temporary directory. Before this temporary directory  is  packed  in  a
       (native)")  but dpkg-source will not do this automatically for you.  If
       you want to continue using the old format, you should be explicit about
       it and put "1.0" in debian/source/format.

   the diff modifies the following upstream files
       When  using  source  format  "1.0"  it  is usually a bad idea to modify
       upstream files directly as the changes end up hidden and mostly undocu-
       mented  in  the .diff.gz file. Instead you should store your changes as
       patches in the debian directory and apply them at build-time. To  avoid
       this  complexity  you can also use the format "3.0 (quilt)" that offers
       this natively.

   cannot represent change to file
       Changes to upstream sources are usually stored with  patch  files,  but
       not  all  changes  can be represented with patches: they can only alter
       the content of plain text files. If you try replacing a file with some-
       thing  of  a  different type (for example replacing a plain file with a
       symlink or a directory), you will get this error message.

   newly created empty file file will not be represented in diff
       Empty files can't be created with patch files. Thus this change is  not
       recorded in the source package and you are warned about it.

   executable mode perms of file will not be represented in diff
   special mode perms of file will not be represented in diff
       Patch  files  do not record permissions of files and thus modified per-
       missions are not stored in the source package. This warning reminds you
       of that fact.

       This  file  contains on a single line the format that should be used to
       build the source package (possible formats  are  described  above).  No
       leading or trailing spaces are allowed.

       This file contains a list of binary files (one per line) that should be
       included in  the  debian  tarball.  Leading  and  trailing  spaces  are
       stripped.   Lines starting with "#" are comments and are skipped. Empty
       lines are ignored.

       This file contains a list of long options that should be  automatically
       prepended  to  the  set  of command line options of a dpkg-source -b or
       dpkg-source --print-format call. Options like --compression and  --com-
       pression-level are well suited for this file.

       Each  option  should  be  put on a separate line. Empty lines and lines
       starting with "#" are ignored. The leading "--" should be stripped  and
       short  options  are not allowed. Optional spaces are allowed around the
       "=" symbol and optional quotes are allowed around the value.  Here's an
       example of such a file:

         # let dpkg-source create a debian.tar.bz2 with maximal compression

       in the generated source package. It can be useful to store a preference
       tied to the maintainer or to the VCS repository where the source  pack-
       age is maintained.

       Free  form  text that is put on top of the automatic patch generated in
       formats "2.0" or "3.0 (quilt)". local-patch-header is not  included  in
       the generated source package while patch-header is.

       This  file  lists  all  patches  that  have to be applied (in the given
       order) on top of the upstream source package. Leading and trailing spa-
       ces are stripped. Lines starting with "#" are comments and are skipped.
       Empty lines are ignored. Remaining lines start with  a  patch  filename
       (relative to the debian/patches/ directory) up to the first space char-
       acter or the end of line. Optional quilt options can follow up  to  the
       end  of  line  or  the  first "#" preceded by one or more spaces (which
       marks the start of a comment up to the end of line).

       The point at which field overriding occurs compared to certain standard
       output field settings is rather confused.
