NAME

       deb-split - Debian multi-part binary package format

SYNOPSIS

       filename.deb

DESCRIPTION

       The  multi-part  .deb format is used to split big packages into smaller pieces to ease transport in small
       media.

FORMAT

       The file is an ar archive with a magic value of !<arch>.  The file names might contain a  trailing  slash
       (since dpkg 1.15.6).

       The  first  member is named debian-split and contains a series of lines, separated by newlines. Currently
       eight lines are present:

       •   The format version number, 2.1 at the time this manual page was written.

       •   The package name.

       •   The package version.

       •   The md5sum of the package.

       •   The total size of the package.

       •   The maximum part size.

       •   The current part number, followed by a slash and the total amount of parts (as in ‘1/10’).

       •   The package architecture (since dpkg 1.16.1).

       Programs which read multi-part archives should be prepared for the minor  format  version  number  to  be
       increased and additional lines to be present, and should ignore these if this is the case.

       If  the  major  format  version  number has changed, an incompatible change has been made and the program
       should stop. If it has not, then the program should be able to safely continue, unless it  encounters  an
       unexpected member in the archive (except at the end), as described below.

       The  second,  last  required member is named data.N, where N denotes the part number. It contains the raw
       part data.

       These members must occur in this exact  order.  Current  implementations  should  ignore  any  additional
       members  after  data.N.   Further  members may be defined in the future, and (if possible) will be placed
       after these two.
