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.
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.
-
-l, --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.
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
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.
- 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.
- /etc/devscripts.conf
- Global devscripts configuration options. Will override
hardcoded defaults.
- ~/.devscripts
- Per-user configuration options. Will override any global
configuration.
