=head1 NAME

|
|
|
dpkg-scanpackages - create Packages index files
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<dpkg-scanpackages>
|
|
[I<option>...] I<binary-path>
|
|
[I<override-file>
|
|
[I<path-prefix>]]
|
|
B<E<gt>>
|
|
I<Packages>
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
B<dpkg-scanpackages>
|
|
sorts through a tree of Debian binary packages and creates a Packages
|
|
file, used by
|
|
L<apt(8)>,
|
|
L<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 media discs.
|
|
You might use
|
|
B<dpkg-scanpackages>
|
|
yourself if making a directory of local packages to install on a cluster
|
|
of machines.
|
|
|
|
B<Note>:
|
|
If you want to access the generated Packages file with
|
|
L<apt(8)>
|
|
you will probably need to compress the file with
|
|
L<xz(1)>
|
|
(generating a Packages.xz file),
|
|
L<bzip2(1)>
|
|
(generating a Packages.bz2 file) or
|
|
L<gzip(1)>
|
|
(generating a Packages.gz file).
|
|
L<apt(8)>
|
|
ignores uncompressed Packages files except on local access (i.e.
|
|
B<file://>
|
|
sources).
|
|
|
|
I<binary-path>
|
|
is the name of the tree of the binary packages to process (for example,
|
|
B<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.
|
|
|
|
I<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
|
|
L<deb-override(5)>.
|
|
|
|
I<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 output.
|
|
If they have the same version and only
|
|
differ in architecture only the first one found is used.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over
|
|
|
|
=item B<-t>, B<--type> I<type>
|
|
|
|
Scan for *.I<type> packages, instead of *.deb.
|
|
|
|
=item B<-e>, B<--extra-override> I<file>
|
|
|
|
Scan I<file> to find supplementary overrides (the file can be
|
|
compressed since dpkg 1.15.5).
|
|
See
|
|
L<deb-extra-override(5)>
|
|
for more information on its format.
|
|
|
|
=item B<-a>, B<--arch> I<arch>
|
|
|
|
Use a pattern consisting of I<*_all.deb> and I<*_arch.deb> instead of
|
|
scanning for all debs.
|
|
|
|
=item B<-h>, B<--hash> I<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: B<md5>, B<sha1>, B<sha256>.
|
|
|
|
=item B<-m>, B<--multiversion>
|
|
|
|
Include all found packages in the output.
|
|
|
|
=item B<-M>, B<--medium> I<id-string>
|
|
|
|
Add an B<X-Medium> field containing the value I<id-string>
|
|
(since dpkg 1.15.5).
|
|
This field is required if you want to generate B<Packages.cd> files
|
|
for use by the B<media> access method of B<dselect>.
|
|
|
|
=item B<-?>, B<--help>
|
|
|
|
Show the usage message and exit.
|
|
|
|
=item B<--version>
|
|
|
|
Show the version and exit.
|

|
|
|
=over
|
|
|
|
=item B<DPKG_COLORS>
|
|
|
|
Sets the color mode (since dpkg 1.18.5).
|
|
The currently accepted values are: B<auto> (default), B<always> and
|
|
B<never>.
|
|
|
|
=item B<DPKG_NLS>
|
|
|
|
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: B<0> and B<1> (default).

|
=head1 DIAGNOSTICS
|
|
|
|
B<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.
