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 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).
