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 https://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 specified, 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 completion.

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

       --list Don't download but just list versions.

       --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.

       --first
              Specify the minimum version of a package which will be downloaded.   Any  versions  which  compare
              larger  than this, according to dpkg, will be considered for download.  May be used in combination
              with --last.

       --last Specify the maximum version of a package which will be downloaded.   Any  package  versions  which
              compare  less  than  this,  according  to  dpkg,  will be considered for download.  May be used in
              combination with --first.

       -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 https://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 downloaded but operations otherwise succeeded as expected.  In some cases
       packages may fail to be downloaded because they are no longer available 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 a specific 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 xterm version but for all architectures.

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

       debsnap -v --first 347-1 --last 348-2 xterm
              Download  source  packages  for  local  architecture  of xterm, between 347-1 and 348-2 revisions,
              inclusive, showing the progress when doing it.

       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.
