       debclean - clean up a sourcecode tree


       debclean [options]


       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
       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.


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

              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.

              Display version and copyright information and exit successfully.


       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:

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

              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).
