NAME

       debsnap - retrieve old snapshots of Debian packages

SYNOPSIS

       debsnap [options] package [version]

       debsnap [-h | --help] [--version]

DESCRIPTION

       debsnap is a tool to help with retrieving snapshots of old packages from a daily archive repository.

       The only publicly available snapshot archive is currently located at http://snapshot.debian.org

       By  default,  debsnap  will download all the available versions for package that are found in the snapshot archive.  If a version is speci-
       fied, only that particular version will be downloaded, if available.

OPTIONS

       The following options are available:

       -d destination, --destdir destination
              Directory to place retrieved packages.

       -f, --force
              Force writing into an existing destination.  By default debsnap will insist the destination directory does not exist yet  unless  it
              is explicitly specified to be '.' (the current working directory).  This is to avoid files being accidentally overwritten by what is
              fetched from the archive and to provide a guarantee for other scripts that only the files fetched will be present there upon comple-
              tion.

       -v, --verbose
              Report  on  the  debsnap  configuration  being  used and progress during the download operation.  Please always use this option when
              reporting bugs.

       --binary
              Download binary packages instead of source packages.

       -a, --architecture
              Specify architecture of downloaded binary packages. Implies --binary.  This can be given multiple times in order to download  binary
              packages for multiple architectures.

       -h, --help
              Show a summary of these options.

       --version
              Show the version of debsnap.

CONFIGURATION OPTIONS

       debsnap may also be configured through the use of the following options in the devscripts configuration files:

       DEBSNAP_VERBOSE
              Same as the command line option --verbose.  Set to yes to enable.

       DEBSNAP_DESTDIR
              Set a default path for the destination directory.  If unset ./source-<package_name> will be used.  The command line option --destdir
              will override this.

       DEBSNAP_BASE_URL
              The base url for the snapshots archive.

              If unset this defaults to http://snapshot.debian.org

EXIT STATUS

       debsnap will return an exit status of 0 if all operations succeeded, 1 if a fatal error occurred, and 2 if some packages failed to be down-
       loaded  but operations otherwise succeeded as expected.  In some cases packages may fail to be downloaded because they are no longer avail-
       able on the snapshot mirror, so any caller should expect this may occur in normal use.

EXAMPLES

       debsnap -a amd64 xterm 256-1
              Download the binary package of specific a xterm version for amd64 architecture.

       debsnap -a armel xterm
              Download binary packages for all versions of xterm for armel architecture.

       debsnap --binary xterm 256-1
              Download binary packages for a specific a xterm version but for all architectures.

       debsnap --binary xterm
              Download binary packages for all version of xterm version for all architectures.

       aptitude search '~i' -F '%p %V' | while read pkg ver; do debsnap -a $(dpkg-architecture -qDEB_HOST_ARCH) -a all $pkg $ver; done
              Download binary packages of all packages that are installed on the system.
