OpenSim.exe Command Line Options
From OpenSimulator
Command line arguments, also known as switches, helpful to modify the behavior of your OpenSimulator for customized environments or debugging.
For End Users
End users of OpenSim will not usually encounter the Simulator command line switches.
For Content Builders
Content builders on OpenSim will not usually encounter the Simulator command line switches.
For Simulator Operators
These can be used on the command line to customize the current startup session, or they can be used in startup scripts.
Switch Syntax
- Windows: "/key:value" or "/key value"
- Unix, Linux "-key=value" or "-key value"
- MacOSX: FIXME
If you want to use a value which contains spaces, contain the entire values and spaces inside of double-quotes(").
Note that "--" switches, like "--key=value" do not work.
It seems a bug in the regular syntax in the external Nini command line parser used by OpenSimulator.
Current Switches
The following command line switches are known:
| Switch | Values | Description | Default |
|---|---|---|---|
| logconfig | String(filepath) | OpenSimulator will configure log4net using this file as configuration file | OpenSim.exe.config |
| background | Boolean | If true, OpenSimulator will run in the background | false |
| inifile | String(filepath) | The path to ini file | OpenSim.ini |
| inimaster | String(filepath) | The path to master ini file | OpenSimDefaults.ini |
| inidirectory | String(filepath) | The path to folder for config ini files. OpenSimulator will read all of *.ini files in this directory and override OpenSim.ini settings. | config |
| physics | "OpenDynamicsEngine", "basicphysics", "POS", "modified_BulletX" | The name of the physics engine. It is the same as physics property in [Startup] section. See OpenSim.ini.example for the detailed information. It will override the settings in OpenSim.ini. | OpenDynamicsEngine |
| gui | Boolean | "old-style" console (deprecated from Opensim 0.7, use -console=basic instead) | false |
| console | "basic","rest" | If "basic", OpenSimulator will launch a simple console capable of processing commands. If "rest", a RestConsole. If others including empty, a console that uses cursor control and context help(default). | (empty) |
| save_crashes | Boolean | If true, OpenSimulator will dump stacktraces into the file in the directory specified with 'crash_dir' when it crashes. Note: As of 0.7.1, it doesn't work. It works in 0.7.2-dev. | false |
| crash_dir | String(filepath) | The path to the directory where crash logs will be created. When OpenSimulator crashes, it will be automatically created if not exists. Note: As of 0.7.1, it doesn't work. It works in 0.7.2-dev. | crashes |
NOTE:
- filepath - The path relative to the working directory of the user or application, in the most cases, it will be bin/.
- Boolean - See #Boolean Aliases below.
Boolean Aliases
Boolean values support several interchangeable aliases starting with OpenSimulator 0.7.2-dev:
- True is the same as On or Yes
- False is the same as Off or No
They are not case-sensitive.
For example, you can type "True", "TRUE" or "tRue"
Related INI File Sections
In the OpenSim.ini and OpenSimDefaults.ini:
[StartUp] ; Set this to true if you want to log crashes to disk ; this can be useful when submitting bug reports. ; However, this will only log crashes within OpenSimulator that cause the entire program to exit ; It will not log crashes caused by virtual machine failures, which includes mono and ODE failures. ; You will need to capture these native stack traces by recording the session log itself. save_crashes = false ; Directory to save crashes to if above is enabled ; (default is /opensimdir/crashes/*.txt or C:\opensim\crashes\*.txt) crash_dir = "crashes"
For Developers
OpenSimulator internally uses Nini as a command line parser.
Command line arguments are parsed in OpenSim/Region/Application/Application.cs
