# Start Parameters

{% hint style="info" %}
Also known as Command-Line Parameters, Command line arguments, or Launch Parameters.
{% endhint %}

Many game servers require *start parameters*, these are command-line options that are set with the server executable when the server starts. 

Using [game server configs](/configuration/game-server-config.md) over parameters is preferred, however, sometimes this is not an option. When this is the case only parameters or a mixture of game server config and parameters will be used.

Parameters being used by the game server can be found in `./gameserver details`. To alter them, you will need to edit [LinuxGSM config files](/configuration/linuxgsm-config.md).

## Predefined Parameters

LinuxGSM often uses predefined parameters that can be edited. This makes adjusting common settings easier and allows them to be displayed in `./gameserver details`.

```
## Predefined Parameters | https://docs.linuxgsm.com/configuration/start-parameters
defaultmap="map_name"
gamemode="game_mode"
maxplayers="42"
port="27015"
sourcetvport="27020"
clientport="27005"
```

## Additional Parameters

Additional command-line parameters can be added to the `startparameters` setting. 

Anything added will be appended to the server executable binary.

### Basic Example

| Parms variable                  | Executable                |
| ------------------------------- | ------------------------- |
| `startparameters="-game nmrih"` | `./srcds_run -game nmrih` |

### Full Example
