DEBDIFF-APPLY(1)            General Commands Manual           DEBDIFF-APPLY(1)

       debdiff-apply - apply a debdiff to a Debian source package

       debdiff-apply [options] [orig_dsc_or_dir] [patch_file]
       debdiff-apply [options] < [patch_file]

       debdiff-apply  takes a patchfile that describes the differences between
       two Debian source packages old and new, and  applies  it  to  a  target
       Debian source package orig.

       orig  could either be the same as old or it could be different.  patch-
       file is expected to be a unified diff between two Debian source  trees,
       as what debdiff(1) normally generates.

       Any  changes to debian/changelog are dealt with specially, to avoid the
       conflicts that changelog diffs typically produce when applied  naively.
       The  exact  behaviour  may  be tweaked in the future, so one should not
       rely on it.

       If patchfile does not apply to orig, even after the  special-casing  of
       debian/changelog,  no  changes  are made and debdiff-apply(1) will exit
       with a non-zero error code.

              Target to apply the patch to. This can  either  be  an  unpacked
              source  tree,  or a .dsc file. In the former case, the directory
              is modified in-place; in the latter case, a second .dsc is  cre-
              ated. Default: .

              Patch  file  to  apply,  in  the  format  output  by debdiff(1).
              Default: /dev/stdin

       -h, --help
              show this help message and exit

       -v, --verbose
              Output more information

       -c CHANGELOG, --changelog CHANGELOG
              Path to debian/changelog; default: debian/changelog

       -D DISTRIBUTION, --distribution DISTRIBUTION
              Distribution to use, if the  patch  doesn't  already  contain  a
              changelog; default: experimental

       --repl Run the python REPL after processing.

              Don't  apply  the  patch;  instead  print out the version of the
              package that it is supposed to be applied to, or nothing if  the
              patch does not specify a source version.

              Don't  apply the patch; instead print out the new version of the
              package debdiff-apply(1)  would  generate,  when  the  patch  is
              applied  to  the  the  given target package, as specified by the
              other arguments.

   For .dsc patch targets:
              Don't clean temporary directories after a failure,  so  you  can
              examine what failed.

              If  the building of the new source package fails, try to refresh
              patches using quilt(1) then try building it again.

       -d DIRECTORY, --directory DIRECTORY
              Extract the .dsc into this directory, which won't be cleaned  up
              after  debdiff-apply(1)  exits.  If  not  given, then it will be
              extracted to a temporary directory.
