deb-split(5) dpkg suite deb-split(5)
deb-split - Debian multi-part binary package format
filename.deb
The multi-part .deb format is used to split big packages into
smaller pieces to ease transport in small media.
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.
deb(5), dpkg-split(1).
