dpkg-scanpackages: create Packages index files
dpkg-scanpackages - create Packages index files
SYNOPSISdpkg-scanpackages [option...] binary-path [override-file [path-prefix]] > Packages
DESCRIPTIONdpkg-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 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 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.
- -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.
- 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).
