NAME
       dpkg-scanpackages - create Packages index files

SYNOPSIS
       dpkg-scanpackages [option...] binary-path [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 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.

       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.

       -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.

       --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.
