SYNC-AVAILABLE(8) Debian administrator's manual SYNC-AVAILABLE(8)NAME
sync-available - sync dpkg's available database with apt's database
SYNOPSIS
sync-available
sync-available --version
sync-available --help
DESCRIPTION
This program updates the dpkg(8) available database with the data in the apt(8) package database. This is required for grep-available(1)
and other similar programs to give up-to-date results.
The same functionality is available through dselect(8), when it is configured to use apt(8) as its acquisition method. However, this pro-
gram does not require that dselect(8) is installed.
EXIT STATUS
The program exits with status code 0 if all went well, and a non-zero status code otherwise.
OPTIONS --version
Output the name and version of the program onto standard output stream.
--help Give a brief usage statement on the standard output stream.
ENVIRONMENT
TMPDIR The name of the directory where temporary files are created. Default is /tmp.
AUTHOR
The program and this manual page were written by Antti-Juhani Kaijanaho <ajk@debian.org>.

dpkg-scanpackages - create Packages index files
SYNOPSIS
dpkg-scanpackages [options] 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 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).
binarydir 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.
overridefile is the name of a file to read which contains information about how the package fits into the distribution (it can be a com-
pressed file); see deb-override(5).
pathprefix 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.
OPTIONS -t, --type type
Scan for *.type packages, instead of *.deb.
-u, --udeb
Obsolete alias for -tudeb.
-e, --extra-override file
Scan file to find supplementary overrides (the file can be compressed). See deb-extra-override(5) for more information on its for-
mat.
-a, --arch arch
Use a pattern consisting of *_all.deb and *_arch.deb instead of scanning for all debs.
-m, --multiversion
Include all found packages in the output.
-M, --medium id-string
Add an X-Medium field containing the value id-string. This field is required if you want to generate Packages.cd files for use by
the multicd access method of dselect.
-h, --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 dupli-
cated, have a Filename field in their control file, are missing from the override file, or have maintainer substitutions which do not take
effect.
