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 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 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 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
-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 anything 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 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).
