dpkg-scanpackages(1) dpkg suite dpkg-scanpackages(1)
dpkg-scanpackages - create Packages index files
dpkg-scanpackages [option...] binary-path [override-file [path-
prefix]] > Packages
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 media discs. 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(8) you will probably need to compress the file with xz(1)
(generating a Packages.xz file), bzip2(1) (generating a
Packages.bz2 file) or gzip(1) (generating a Packages.gz file).
apt(8) ignores uncompressed Packages files except on local access
(i.e. file:// sources).
binary-path 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 (the
file can be compressed since dpkg 1.15.5); 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.
-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 since dpkg 1.15.5). 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.
-h, --hash hash-list
Only generate file hashes for the comma-specified list
specified (since dpkg 1.17.14). The default is to generate
all currently supported hashes. Supported values: md5, sha1,
sha256.
-m, --multiversion
Include all found packages in the output.
-M, --medium id-string
Add an X-Medium field containing the value id-string (since
dpkg 1.15.5). This field is required if you want to generate
Packages.cd files for use by the media access method of
dselect.
-?, --help
Show the usage message and exit.
--version
Show the version and exit.
DPKG_COLORS
Sets the color mode (since dpkg 1.18.5). The currently
accepted values are: auto (default), always and never.
DPKG_NLS
If set, it will be used to decide whether to activate Native
Language Support, also known as internationalization (or i18n)
support (since dpkg 1.19.0). The accepted values are: 0 and 1
(default).
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.
