NAME dpkg-scanpackages - create Packages index files
SYNOPSIS dpkg-scanpackages [option...] binary-dir [override-file [path-prefix]] > Packages
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 xz(1) (generating a Packages.xz file), bzip2(1) (generating a Pack‐ ages.bz2 file) or gzip(1) (generating a Packages.gz file). apt ignores uncompressed Pack‐ ages 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, con‐ trib/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 pack‐ age 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 out‐ put. 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 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 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.
