NAME

   debclean - clean up a sourcecode tree

SYNOPSIS

   debclean [options]

DESCRIPTION

   debclean  walks  through  the  directory tree starting at the directory
   tree in which it was invoked, and executes debian/rules clean for  each
   Debian  source directory encountered.  These directories are recognised
   by containing a debian/changelog file for a package whose name  matches
   that of the directory.  Name matching is described below.

   Also,  if  the  --cleandebs  option  is  given, then in every directory
   containing a Debian source tree, all files named *.deb,  *.changes  and
   *.build  are  removed.  The .dsc, .diff.gz and the (.orig).tar.gz files
   are not touched so that the release can be reconstructed if  necessary,
   and  the  .upload files are left so that debchange functions correctly.
   The --nocleandebs option prevents this extra cleaning behaviour and the
   --cleandebs option forces it.  The default is not to clean these files.

   debclean uses debuild(1) to clean the source tree.

Directory name checking

   In  common  with  several  other  scripts  in  the  devscripts package,
   debclean  will  walk  through  the   directory   tree   searching   for
   debian/changelog  files.   As  a  safeguard against stray files causing
   potential problems, it will examine the name of  the  parent  directory
   once  it  finds  a  debian/changelog file, and check that the directory
   name corresponds to the package name.  Precisely how it  does  this  is
   controlled      by      two      configuration      file      variables
   DEVSCRIPTS_CHECK_DIRNAME_LEVEL and DEVSCRIPTS_CHECK_DIRNAME_REGEX,  and
   their  corresponding  command-line  options  --check-dirname-level  and
   --check-dirname-regex.

   DEVSCRIPTS_CHECK_DIRNAME_LEVEL can take the following values:

   0      Never check the directory name.

   1      Only check the directory name if we have had to change directory
          in  our  search  for  debian/changelog.   This  is  the  default
          behaviour.

   2      Always check the directory name.

   The directory name is checked by testing whether the current  directory
   name  (as  determined  by  pwd(1))  matches  the  regex  given  by  the
   configuration file  option  DEVSCRIPTS_CHECK_DIRNAME_REGEX  or  by  the
   command  line option --check-dirname-regex regex.  Here regex is a Perl
   regex (see perlre(3perl)), which will be anchored at the beginning  and
   the  end.   If  regex  contains  a  '/',  then  it  must match the full
   directory path.  If not, then it must match the  full  directory  name.
   If  regex  contains  the string PACKAGE', this will be replaced by the
   source package name, as determined from  the  changelog.   The  default
   value  for the regex is: PACKAGE(-.+)?', thus matching directory names
   such as PACKAGE and PACKAGE-version.

OPTIONS

   --cleandebs
          Also remove all .deb, .changes and .build files from the  parent
          directory.

   --nocleandebs
          Do  not  remove  the  .deb,  .changes  and .build files from the
          parent directory; this is the default behaviour.

   --check-dirname-level N
          See the above section Directory name checking for an explanation
          of this option.

   --check-dirname-regex regex
          See the above section Directory name checking for an explanation
          of this option.

   --no-conf, --noconf
          Do not read any configuration files.  This can only be  used  as
          the first option given on the command-line.

   -d     Do not run dpkg-checkbuilddeps to check build dependencies.

   --help Display a help message and exit successfully.

   --version
          Display version and copyright information and exit successfully.

CONFIGURATION VARIABLES

   The  two configuration files /etc/devscripts.conf and ~/.devscripts are
   sourced in that order to set  configuration  variables.   Command  line
   options   can   be   used  to  override  configuration  file  settings.
   Environment variable  settings  are  ignored  for  this  purpose.   The
   currently recognised variables are:

   DEBCLEAN_CLEANDEBS
          If  this  is  set to yes, then it is the same as the --cleandebs
          command line parameter being used.

   DEVSCRIPTS_CHECK_DIRNAME_LEVEL, DEVSCRIPTS_CHECK_DIRNAME_REGEX
          See the above section Directory name checking for an explanation
          of   these   variables.    Note   that  these  are  package-wide
          configuration  variables,  and   will   therefore   affect   all
          devscripts  scripts  which  check  their  value, as described in
          their respective manpages and in devscripts.conf(5).
