NAME         top

       dpkg-scanpackages - create Packages index files

SYNOPSIS         top

       dpkg-scanpackages [option...] binary-path [override-file [path-
       prefix]] > Packages

DESCRIPTION         top

       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

       Note: If you want to access the generated Packages file with apt
       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 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

       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

       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         top

       -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 multicd
              access method of dselect.

       -?, --help
              Show the usage message and exit.

              Show the version and exit.

ENVIRONMENT         top

              Sets the color mode (since dpkg 1.18.5).  The currently
              accepted values are: auto (default), always and never.

              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).

DIAGNOSTICS         top

       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.
