debc - view contents of a generated Debian package
debc [
options] [
changes file] [
package ...]
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.
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.
-
-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.
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).
