			</argument>
			<argument index="1" name="arguments" type="PackedStringArray">

			<description>
				Creates a new process that runs independently of Godot. It will not terminate if Godot terminates. The file specified in [code]path[/code] must exist and be executable. Platform path resolution will be used. The [code]arguments[/code] are used in the given order and separated by a space.
				If the process creation succeeds, the method will return the new process ID, which you can use to monitor the process (and potentially terminate it with [method kill]). If the process creation fails, the method will return [code]-1[/code].
				For example, running another instance of the project:
				[codeblocks]
				[gdscript]
				var pid = OS.create_process(OS.get_executable_path(), [])
				[/gdscript]
				[csharp]
				var pid = OS.CreateProcess(OS.GetExecutablePath(), new string[] {});
				[/csharp]
				[/codeblocks]
				See [method execute] if you wish to run an external command and retrieve the results.
				[b]Note:[/b] This method is implemented on Android, iOS, Linux, macOS and Windows.

			<argument index="3" name="read_stderr" type="bool" default="false">

			<description>
				Executes a command. The file specified in [code]path[/code] must exist and be executable. Platform path resolution will be used. The [code]arguments[/code] are used in the given order and separated by a space. If an [code]output[/code] [Array] is provided, the complete shell output of the process will be appended as a single [String] element in [code]output[/code]. If [code]read_stderr[/code] is [code]true[/code], the output to the standard error stream will be included too.
				If the command is successfully executed, the method will return the exit code of the command, or [code]-1[/code] if it fails.
				[b]Note:[/b] The Godot thread will pause its execution until the executed command terminates. Use [Thread] to create a separate thread that will not pause the Godot thread, or use [method create_process] to create a completely independent process.
				For example, to retrieve a list of the working directory's contents:
				[codeblocks]
				[gdscript]
				var output = []
				var exit_code = OS.execute("ls", ["-l", "/tmp"], output)
				[/gdscript]
				[csharp]
				var output = new Godot.Collections.Array();
				int exitCode = OS.Execute("ls", new string[] {"-l", "/tmp"}, output);
				[/csharp]
				[/codeblocks]
				To execute a composite command, a platform-specific shell can be invoked. For example:
				[codeblocks]
				[gdscript]
				var output = []
				OS.execute("CMD.exe", ["/C", "cd %TEMP% &amp;&amp; dir"], output)
				[/gdscript]
				[csharp]
				var output = new Godot.Collections.Array();
				OS.Execute("CMD.exe", new string[] {"/C", "cd %TEMP% &amp;&amp; dir"}, output);
				[/csharp]
				[/codeblocks]
				[b]Note:[/b] This method is implemented on Android, iOS, Linux, macOS and Windows.

			</description>
		</method>
		<method name="get_cmdline_args">
			<return type="PackedStringArray">

			<description>
				Returns the command-line arguments passed to the engine.
				Command-line arguments can be written in any form, including both [code]--key value[/code] and [code]--key=value[/code] forms so they can be properly parsed, as long as custom command-line arguments do not conflict with engine arguments.
				You can also incorporate environment variables using the [method get_environment] method.
				You can set [code]editor/main_run_args[/code] in the Project Settings to define command-line arguments to be passed by the editor when running the project.
				Here's a minimal example on how to parse command-line arguments into a dictionary using the [code]--key=value[/code] form for arguments:
				[codeblocks]
				[gdscript]
				var arguments = {}
				for argument in OS.get_cmdline_args():
				    if argument.find("=") &gt; -1:
				        var key_value = argument.split("=")
				        arguments[key_value[0].lstrip("--")] = key_value[1]
				[/gdscript]
				[csharp]
				var arguments = new Godot.Collections.Dictionary();
				foreach (var argument in OS.GetCmdlineArgs())
				{
				    if (argument.Find("=") &gt; -1)
				    {
				        string[] keyValue = argument.Split("=");
				        arguments[keyValue[0].LStrip("--")] = keyValue[1];
				    }
				}
				[/csharp]
				[/codeblocks]
