deb-old(5) dpkg suite deb-old(5)
deb-old - old style Debian binary package format
filename.deb
The .deb format is the Debian binary package file format. This
manual page describes the old format, used before Debian 0.93.
Please see deb(5) for details of the new format.
The file is two lines of format information as ASCII text,
followed by two concatenated gzipped ustar files.
The first line is the format version number padded to 8 digits,
and is 0.939000 for all old-format archives.
The second line is a decimal string (without leading zeroes)
giving the length of the first gzipped tarfile.
Each of these lines is terminated with a single newline character.
The first tarfile contains the control information, as a series of
ordinary files. The file control must be present, as it contains
the core control information.
In some very old archives, the files in the control tarfile may
optionally be in a DEBIAN subdirectory. In that case, the DEBIAN
subdirectory will be in the control tarfile too, and the control
tarfile will have only files in that directory. Optionally the
control tarfile may contain an entry for ‘.’, that is, the current
directory.
The second gzipped tarfile is the filesystem archive, containing
pathnames relative to the root directory of the system to be
installed on. The pathnames do not have leading slashes.
deb(5), deb-control(5), dpkg-deb(1).
This page is part of the dpkg (Debian Package Manager) project.
