| **Argument**                                              | **Description**                                                                                                                                                                                                                                                                                                                                                                                 | **Use with**                            |
| --------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------- |
| `-nolog`                                                  | Disables the log output completely.                                                                                                                                                                                                                                                                                                                                                             | standard log output                     |
| `-logfile [path/to/logfile]`                              | Routes the Player log output including `stderr` to the specified log file. You can use this parameter to get trace information when the logging plug-in initializes. The log file path set using this argument has a precedence over the path set using `-platform-hmi-player-datapath`.**Note:** If the specified file path has write restrictions, the Unity Player exits with an error code. | standard log output and logging plug-in |
| `-logfile -`                                              | Forces the Player to route the log output including `stderr` to the console through `stdout` instead of writing to the specified file. You can use this parameter to get trace information when the logging plug-in initializes.                                                                                                                                                                | standard log output and logging plug-in |
| `-logflush`                                               | Synchronizes the log output with every log event, which can be helpful in crash investigations.                                                                                                                                                                                                                                                                                                 | standard log output                     |
| `-platform-hmi-log-plugin [plugin.so]`                    | Specifies the logging plug-in's shared library. Needs to be located in the Plugins folder.                                                                                                                                                                                                                                                                                                      | logging plug-in                         |
| `-platform-hmi-log-plugin [" "]`                          | Disables the configured logging plug-in temporarily.                                                                                                                                                                                                                                                                                                                                            | logging plug-in                         |
| `-platform-hmi-log-disable-on-plugin-failure`             | Disables the log output when the logging plug-in fails to initialize.                                                                                                                                                                                                                                                                                                                           | logging plug-in                         |
| `-platform-hmi-player-datapath [path/to/writable/folder]` | Specifies the path where the Player log output is saved as persistent data. By default, Unity uses the value of `HOME` environment variable to set this path to your system's home directory. You can configure this path through **Player Settings** > **Other Settings** > **Configuration** > **Player Data path**.                                                                          | standard log output                     |
