Options
-------

+----------------------------------------+---------------------------------------------------------------------------------------------------------------------+
| ``--porcelain``                        | Streamlined and stable output for input into other tools                                                            |
+----------------------------------------+---------------------------------------------------------------------------------------------------------------------+
| ``--ignore-errors``                    | Ignore errors (report them as warnings) and continue processing wherever possible                                   |
+----------------------------------------+---------------------------------------------------------------------------------------------------------------------+
| ``--raw``                              | | Don't apply (contextual) expansion and checking on requests.                                                      |
|                                        | | Keys and values passed must match those used internally to the FDB exactly.                                       |
|                                        | | This prevents the use of named parameters (such as t rather than param=130), dates (such as date=-1), or similar. |
+----------------------------------------+---------------------------------------------------------------------------------------------------------------------+
| ``--minimum-keys``                     | | Default is class,expver                                                                                           |
|                                        | | Define the minimum set of keys that must be specified. This prevents inadvertently exploring the entire FDB.      |
+----------------------------------------+---------------------------------------------------------------------------------------------------------------------+
| ``--all``                              | (Debug and testing only) Visit all FDB databases                                                                    |
+----------------------------------------+---------------------------------------------------------------------------------------------------------------------+
| ``--config=string``                    | FDB configuration filename                                                                                          |
