@ -37,3 +37,252 @@ 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

Restic and json
|
||||
***************
|
||||
|
||||
Restic can output json data if requested with the ``--json`` flag.
|
||||
The structure of that data varies depending on the circumstance. The
|
||||
json output of Most restic commands are documented here.
|
||||
|
||||
.. note::
|
||||
Not all commands support json output. If a command does not support json output,
|
||||
at the time of writing, it is not supported yet. (feel free to submit a pull request!)
