NAME

       deb-old - old style Debian binary package format

SYNOPSIS

       filename.deb

DESCRIPTION

       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.

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.
