The standard UNIX-style ordering of command-line arguments places optional flags before other positional arguments. All of restic's commands support this ordering, but some of the usage strings showed the flags after the positional arguments (which restic also parses just fine). This change updates the doc strings to reflect the standard ordering. Because the `restic help` command comes directly from Cobra, there does not appear to be a way to update the argument ordering in its usage string, so it maintains the non-standard ordering (positional arguments before optional flags).

Packages
|
||
********
|
||
|
||
Note that if at any point the package you’re trying to use is outdated, you
|
||
always have the option to use an official binary from the restic project.
|
||
|
||
These are up to date binaries, built in a reproducible and verifiable way, that
|
||
you can download and run without having to do additional installation work.
|
||
|
||
Please see the :ref:`official_binaries` section below for various downloads.
|
||
Official binaries can be updated in place by using the ``restic self-update``
|
||
command.

Official Binaries
|
||
*****************
|
||
|
||
Stable Releases
|
||
===============
|
||
|
||
You can download the latest stable release versions of restic from the `restic
|
||
release page <https://github.com/restic/restic/releases/latest>`__. These builds
|
||
are considered stable and releases are made regularly in a controlled manner.
|
||
|
||
There's both pre-compiled binaries for different platforms as well as the source
|
||
code available for download. Just download and run the one matching your system.
|
||
|
||
The official binaries can be updated in place using the ``restic self-update``
|
||
command (needs restic 0.9.3 or later):
|
||
|
||
.. code-block:: console
|
||
|
||
$ restic version
|
||
restic 0.9.3 compiled with go1.11.2 on linux/amd64
|
||
|
||
$ restic self-update
|
||
find latest release of restic at GitHub
|
||
latest version is 0.9.4
|
||
download file SHA256SUMS
|
||
download SHA256SUMS
|
||
download file SHA256SUMS
|
||

|
||

|
||
downloaded restic_0.9.4_linux_amd64.bz2
|
||

|
||
successfully updated restic to version 0.9.4
|
||
|
||
$ restic version
|
||
restic 0.9.4 compiled with go1.12.1 on linux/amd64
|
||
|
||
The ``self-update`` command uses the GPG signature on the files uploaded to
|
||
GitHub to verify their authenticity. No external programs are necessary.
|
||
|
||
.. note:: Please be aware that the user executing the ``restic self-update``
|
||
command must have the permission to replace the restic binary.
|
||
If you want to save the downloaded restic binary into a different file, pass
|
||
the file name via the option ``--output``.
|
||
|
||
Unstable Builds
|
||
===============
|
||
|
||
Another option is to use the latest builds for the master branch, available on
|
||
the `restic beta download site
|
||
<https://beta.restic.net/?sort=time&order=desc>`__. These too are pre-compiled
|
||
and ready to run, and a new version is built every time a push is made to the
|
||
master branch.
|
||
|
||
Windows
|
||
=======
|
||
|
||
On Windows, put the `restic.exe` binary into `%SystemRoot%\\System32` to use restic
|
||
in scripts without the need for absolute paths to the binary. This requires
|
||
administrator rights.
|
||
|
||
Docker Container
|
||
****************
|
||
|
||
We're maintaining a bare docker container with just a few files and the restic
|
||
binary, you can get it with `docker pull` like this:
|
||
|
||
.. code-block:: console
|
||
|
||
$ docker pull restic/restic
|
||
|
||
.. note::
|
||
| Another docker container which offers more configuration options is
|
||
| available as a contribution (Thank you!). You can find it at
|
||
| https://github.com/Lobaro/restic-backup-docker
|
||
|
||
From Source
|
||
***********
|
||
|
||
restic is written in the Go programming language and you need at least
|
||
Go version 1.12. Building restic may also work with older versions of Go,
|
||
but that's not supported. See the `Getting
|
||
started <https://golang.org/doc/install>`__ guide of the Go project for
|
||
instructions how to install Go.
|
||
|
||
In order to build restic from source, execute the following steps:
|
||
|
||
.. code-block:: console
|
||
|
||
$ git clone https://github.com/restic/restic
|
||
[...]
|
||
|
||
$ cd restic
|
||
|
||
$ go run build.go
|
||
|
||
You can easily cross-compile restic for all supported platforms, just
|
||
supply the target OS and platform via the command-line options like this
|
||
(for Windows and FreeBSD respectively):
|
||
|
||
.. code-block:: console
|
||
|
||
$ go run build.go --goos windows --goarch amd64
|
||
|
||
$ go run build.go --goos freebsd --goarch 386
|
||
|
||
$ go run build.go --goos linux --goarch arm --goarm 6
|
||
|
||
The resulting binary is statically linked and does not require any
|
||
libraries.
|
||
|
||
At the moment, the only tested compiler for restic is the official Go
|
||
compiler. Building restic with gccgo may work, but is not supported.
|
||
|
||
Autocompletion
|
||
**************
|
||
|
||
Restic can write out man pages and bash/zsh compatible autocompletion scripts:
|
||
|
||
.. code-block:: console
|
||
|
||
$ ./restic generate --help
|
||
|
||
The "generate" command writes automatically generated files (like the man pages
|
||
and the auto-completion files for bash and zsh).
|
||
|
||
Usage:
|
||
restic generate [flags] [command]
|
||
|
||
Flags:
|
||
--bash-completion file write bash completion file
|
||
-h, --help help for generate
|
||
--man directory write man pages to directory
|
||
--zsh-completion file write zsh completion file
|
||
|
||
Example for using sudo to write a bash completion script directly to the system-wide location:
|
||
|
||
.. code-block:: console
|
||
|
||
$ sudo ./restic generate --bash-completion /etc/bash_completion.d/restic
|
||
writing bash completion file to /etc/bash_completion.d/restic
|
