description
dpkg-scanpackages
sorts through a tree of Debian binary packages and creates a
Packages file, used by apt(8), dselect(1),
etc, to tell the user what packages are available for
installation. These Packages files are the same as those
found on Debian archive sites and CD-ROMs. You might use
dpkg-scanpackages yourself if making a
directory of local packages to install on a cluster of
machines.
Note: If
you want to access the generated Packages file with
apt you will probably need to compress the file with
bzip2(1) (generating a Packages.bz2 file) or
gzip(1) (generating a Packages.gz file). apt ignores
uncompressed Packages files except on local access (i.e.
file:// sources).
binary-dir
is the name of the tree of the binary packages to process
(for example, contrib/binary-i386). It is best
to make this relative to the root of the Debian archive,
because every Filename field in the new Packages file will
start with this string.
override-file
is the name of a file to read which contains information
about how the package fits into the distribution (it can be
a compressed file); see deb-override(5).
path-prefix
is an optional string to be prepended to the Filename
fields.
If more than
one version of a package is found only the newest one is
included in the output. If they have the same version and
only differ in architecture only the first one found is
used.
options
-t,
--type type
Scan for *.type
packages, instead of *.deb.
-e,
--extra-override file
Scan file to find
supplementary overrides (the file can be compressed). See
deb-extra-override(5) for more
information on its format.
-a,
--arch arch
Use a pattern consisting of
*_all.deb and *_arch.deb instead of scanning
for all debs.
-m,
--multiversion
Include all found packages in
the output.
-M,
--medium id-string
Add an X-Medium field
containing the value id-string. This field is
required if you want to generate Packages.cd files
for use by the multicd access method of dselect.
-?,
--help
Show the usage message and
exit.
--version
Show the version and exit.
diagnostics
dpkg-scanpackages outputs the usual self-explanatory
errors. It also warns about packages that are in the wrong
subdirectory, are duplicated, have a Filename field in their
control file, are missing from the override file, or have
maintainer substitutions which do not take effect.
