dpkg-scanpackages - create Packages index files
]] > Packages
sorts through a tree of Debian binary packages and
creates a Packages file, used by apt(8)
, 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.
If you want to access the generated Packages file with apt
you will probably need to compress the file with xz(1)
Packages.xz file), bzip2(1)
(generating a Packages.bz2 file) or
(generating a Packages.gz file). apt ignores uncompressed
Packages files except on local access (i.e. file://
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.
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)
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,
- -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 multicd access method
- -?, --help
- Show the usage message and exit.
- Show the version and exit.
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.
