<H2>DESCRIPTION</H2>
|
|
|
|
<B>dpkg-scanpackages</B>
|
|
|
|
sorts through a tree of Debian binary packages and creates a Packages
|
|
file, used by
|
|
<B><A HREF="/cgi-bin/man/man2html?8+apt">apt</A></B>(8),
|
|
|
|
<B><A HREF="/cgi-bin/man/man2html?1+dselect">dselect</A></B>(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
|
|
<B>dpkg-scanpackages</B>
|
|
|
|
yourself if making a directory of local packages to install on a cluster
|
|
of machines.
|
|
<P>
|
|
|
|
<B>Note:</B>
|
|
|
|
If you want to access the generated Packages file with
|
|
<B>apt</B>
|
|
|
|
you will probably need to compress the file with
|
|
<B><A HREF="/cgi-bin/man/man2html?1+xz">xz</A></B>(1)
|
|
|
|
(generating a Packages.xz file),
|
|
<B><A HREF="/cgi-bin/man/man2html?1+bzip2">bzip2</A></B>(1)
|
|
|
|
(generating a Packages.bz2 file) or
|
|
<B><A HREF="/cgi-bin/man/man2html?1+gzip">gzip</A></B>(1)
|
|
|
|
(generating a Packages.gz file). apt ignores uncompressed Packages
|
|
files except on local access (i.e.
|
|
<B>file://</B>
|
|
|
|
sources).
|
|
<P>
|
|
|
|
<I>binary-path</I>
|
|
|
|
is the name of the tree of the binary packages to process (for example,
|
|
<B>contrib/binary-i386</B>).
|
|
|
|
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.
|
|
<P>
|
|
|
|
<I>override-file</I>
|
|
|
|
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
|
|
<B><A HREF="/cgi-bin/man/man2html?5+deb-override">deb-override</A></B>(5).
|
|
|
|
<P>
|
|
|
|
<I>path-prefix</I>
|
|
|
|
is an optional string to be prepended to the Filename fields.
|
|
<P>
|
|
|
|
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.
