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 information 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  pro-
       gram 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 ensuring 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
       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  con-
       figuration  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.

       --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
       options can be used to override configuration file settings.  Environment variable settings are ignored for this  purpose.   The  currently
       recognised 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 configuration
              variables,  and  will therefore affect all devscripts scripts which check their value, as described in their respective manpages and
              in devscripts.conf(5).
