NAME

6       dpkg-scanpackages - create Packages index files
7

SYNOPSIS

9       dpkg-scanpackages [option...] binary-path [override-file [path-prefix]]
10       > Packages
11

DESCRIPTION

13       dpkg-scanpackages sorts through a tree of Debian binary packages and
14       creates a Packages file, used by apt(8), dselect(1), etc, to tell the
15       user what packages are available for installation. These Packages files
16       are the same as those found on Debian archive sites and CD-ROMs. You
17       might use dpkg-scanpackages yourself if making a directory of local
18       packages to install on a cluster of machines.
19
20       Note: If you want to access the generated Packages file with apt(8) you
21       will probably need to compress the file with xz(1) (generating a
22       Packages.xz file), bzip2(1) (generating a Packages.bz2 file) or gzip(1)
23       (generating a Packages.gz file).  apt(8) ignores uncompressed Packages
24       files except on local access (i.e.  file:// sources).
25
26       binary-path is the name of the tree of the binary packages to process
27       (for example, contrib/binary-i386).  It is best to make this relative
28       to the root of the Debian archive, because every Filename field in the
29       new Packages file will start with this string.
30
31       override-file is the name of a file to read which contains information
32       about how the package fits into the distribution (the file can be
33       compressed since dpkg 1.15.5); see deb-override(5).
34
35       path-prefix is an optional string to be prepended to the Filename
36       fields.
37
38       If more than one version of a package is found only the newest one is
39       included in the output. If they have the same version and only differ
40       in architecture only the first one found is used.
41

OPTIONS

43       -t, --type type
44           Scan for *.type packages, instead of *.deb.
45
46       -e, --extra-override file
47           Scan file to find supplementary overrides (the file can be
48           compressed since dpkg 1.15.5).  See deb-extra-override(5) for more
49           information on its format.
50
51       -a, --arch arch
52           Use a pattern consisting of *_all.deb and *_arch.deb instead of
53           scanning for all debs.
54
55       -h, --hash hash-list
56           Only generate file hashes for the comma-specified list specified
57           (since dpkg 1.17.14).  The default is to generate all currently
58           supported hashes.  Supported values: md5, sha1, sha256.
59
60       -m, --multiversion
61           Include all found packages in the output.
62
63       -M, --medium id-string
64           Add an X-Medium field containing the value id-string (since dpkg
65           1.15.5).  This field is required if you want to generate
66           Packages.cd files for use by the multicd access method of dselect.
67
68       -?, --help
69           Show the usage message and exit.
70
71       --version
72           Show the version and exit.
73

ENVIRONMENT

75       DPKG_COLORS
76           Sets the color mode (since dpkg 1.18.5).  The currently accepted
77           values are: auto (default), always and never.
78
79       DPKG_NLS
80           If set, it will be used to decide whether to activate Native
81           Language Support, also known as internationalization (or i18n)
82           support (since dpkg 1.19.0).  The accepted values are: 0 and 1
83           (default).
84

DIAGNOSTICS

86       dpkg-scanpackages outputs the usual self-explanatory errors. It also
87       warns about packages that are in the wrong subdirectory, are
88       duplicated, have a Filename field in their control file, are missing
89       from the override file, or have maintainer substitutions which do not
90       take effect.
