Using Client Parameters

There are many ways of passing command line options to the viewer. These are among the most common and useful:

Command Line

From all supported platforms, arguments may be specified manually when running the viewer from a shell.

Windows Shortcuts

Create a shortcut to the SecondLife.exe executable. Edit the shortcut properties and add any of the above options in the first editable text field. The arguments go at the end of the line, *after* the closing quotation mark, if any.

Linux

Open the gridargs.dat file found in your Second Life folder, using your favorite text editor. Add any of the above options to the file, separated either by a space or a newline. Save the file. The next time Second Life is launched, it will be launched with the added options.

OS X Parameter File

In OS X, create a file called Second Life.app/Contents/Resources/arguments.txt and list the options you like, one per line.

OS X Applescripts

An alternative (and often easier) way to launch Second Life is to use an AppleScript. To do this, go into /Applications/AppleScript and open Script Editor. Open a new document and paste the following text into it:

do shell script "\"/Applications/Second Life.app/Contents/MacOS/Second Life\" -grid Aditi"

The script includes a parameter as an example, which will send you to the beta grid, change the parameters as you please. Once you're happy with the parameters, hit the "Compile" button, then go to File -> Save As, and save the script as an Application, and select "Run Only" (may be "Execute" on OS X.4 Tiger). If you want to tweak the script then you can save it as not run-only, and/or save a copy as "Script".

Now simply double-click the Application you've compiled, and SL will launch with the parameters you chose. NOTE: If SL launches then immediately quits, them you will need to open it normally as there is likely an update available, so download it and your script will work again, there is a Jira issue for this.

Visual Studio

In Visual Studio, the command line paramaters are in the Debug Options pane of the newview project preferences. Ensure newview is your startup project, and launch the compiled viewer from within the debugger for these options to take effect.

XCode

In XCode, first select "newview" under the "Executables" group in XCode. Then open the "Get Info" dialog and click the "Arguments" tab. Add any of the above options to the "Arguments to be passed on launch" pane.

Specifying new command line parameters

New command line parameters can be added to the client via the configuration file app_settings/cmd_line.xml. Using this file a command line paramter can be mapped to a user setting. Parameter can have the following options:

• desc - A description of the paramter.
• short - a single character to map to the paramter.
• count - the number of tokens to follow a option.
• compose - true if the option can be specified multiple times.
• positional - true if the option can be specified without --name.
• last_option - true if the option should be the last option.
• map-to - specify a user setting to map the option to.

The file uses LLSD syntax. Use the existing options as reference.
