********************************************
You may find a need to check if a repository is already initialized,
perhaps to prevent your script from initializing a repository multiple
times. The command ``cat config`` may be used for this purpose:
perhaps to prevent your script from trying to initialize a repository multiple
times (the ``init`` command contains a check to prevent overwriting existing
repositories). The command ``cat config`` may be used for this purpose:
.. code-block:: console
$ restic -r /srv/restic-repo cat config
Fatal: unable to open config file: stat /srv/restic-repo/config: no such file or directory
Fatal: repository does not exist: unable to open config file: stat /srv/restic-repo/config: no such file or directory
Is there a repository at the following location?
/srv/restic-repo
If a repository does not exist, restic will return a non-zero exit code
and print an error message. Note that restic will also return a non-zero
exit code if a different error is encountered (e.g.: incorrect password
to ``cat config``) and it may print a different error message. If there
are no errors, restic will return a zero exit code and print the repository
If a repository does not exist, restic (since 0.17.0) will return exit code ``10``
and print a corresponding error message. Older versions return exit code ``1``.
Note that restic will also return exit code ``1`` if a different error is encountered
(e.g.: incorrect password to ``cat config``) and it may print a different error message.
If there are no errors, restic will return a zero exit code and print the repository
metadata.
