DEBC(1)                     General Commands Manual                    DEBC(1)

NAME
       debc - view contents of a generated Debian package

SYNOPSIS
       debc [options] [changes file] [package ...]

DESCRIPTION
       debc figures out the current version of a package and displays informa-
       tion about the .deb and .udeb files which have been  generated  in  the
       current  build process.  If a .changes file is specified on the command
       line, the filename must end with .changes, as this is how  the  program
       distinguishes  it  from  package  names.   If  not, then debc has to be
       called from within the source code directory tree.  In  this  case,  it
       will  look  for  the .changes file corresponding to the current package
       version (by determining the name and version number from the changelog,
       and the architecture in the same way as dpkg-buildpackage(1) does).  It
       then runs dpkg-deb -I and dpkg-deb -c on every .deb and  .udeb  archive
       listed  in  the .changes file to display information about the contents
       of the .deb / .udeb files.  It precedes every .deb or .udeb  file  with
       the name of the file.  It assumes that all of the .deb / .udeb archives
       live  in the same directory as the .changes file.  It is useful for en-
       suring that the expected files have ended up in the Debian package.

       If  a  list  of  packages is given on the command line, then only those
       debs or udebs with names in this list of packages will be processed.

Directory name checking
       In common with several other scripts in the  devscripts  package,  debc
       will  climb  the directory tree until it finds a debian/changelog file.
       As a safeguard against stray files causing potential problems, it  will
       examine  the  name  of  the  parent  directory  once  it  finds the de-
       bian/changelog file, and check that the directory name  corresponds  to
       the package name.  Precisely how it does this is controlled by two con-
       figuration  file  variables  DEVSCRIPTS_CHECK_DIRNAME_LEVEL   and   DE-
       VSCRIPTS_CHECK_DIRNAME_REGEX,  and their corresponding command-line op-
       tions --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 behav-
              iour.

       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 configu-
       ration 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
       -adebian-architecture, -tGNU-system-type
              See dpkg-architecture(1) for a  description  of  these  options.
              They affect the search for the .changes file.  They are provided
              to mimic the behaviour of dpkg-buildpackage when determining the
              name of the .changes file.

       --debs-dir directory
              Look for the .changes, .deb and .udeb files in directory instead
              of the parent of the source directory.  This should either be an
              absolute path or relative to the top of the source directory.

       --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.

       --list-changes
              List  the filename of the .changes file, and do not display any-
              thing else. This option only makes sense if a .changes  file  is
              NOT  passed explicitly in the command line. This can be used for
              example in a script that needs to reference the  .changes  file,
              without  having  to duplicate the heuristics for finding it that
              debc already implements.

       --list-debs
              List the filenames of the .deb  packages,  and  do  not  display
              their contents.

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

       --help, --version
              Show help message and version information respectively.

CONFIGURATION VARIABLES
       The two configuration files /etc/devscripts.conf and ~/.devscripts  are
       sourced in that order to set configuration variables.  Command line op-
       tions can be used to override configuration file settings.  Environment
       variable  settings  are ignored for this purpose.  The currently recog-
       nised variables are:

       DEBRELEASE_DEBS_DIR
              This specifies the directory in which to look for the  .changes,
              .deb and .udeb files, and is either an absolute path or relative
              to the  top  of  the  source  tree.   This  corresponds  to  the
              --debs-dir  command  line option.  This directive could be used,
              for example, if you always use pbuilder or  svn-buildpackage  to
              build your packages.  Note that it also affects debrelease(1) in
              the same way, hence the strange name of the option.

       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 configura-
              tion variables, and will therefore affect all devscripts scripts
              which  check  their value, as described in their respective man-
              pages and in devscripts.conf(5).
