The command "openttd -g ${filename}" is used to start the OpenTTD (Open Transport Tycoon Deluxe) game and load a specific game save file.

Here's the breakdown of the command:

• "openttd": This is the executable file or command name for running the OpenTTD game.
• "-g": It is a command-line option that indicates that a game save file is going to be loaded.
• "${filename}": This is a placeholder for the actual filename of the game save file. The "$" symbol and curly braces "{}" are used to indicate a variable. The variable named "filename" needs to be replaced with the actual name of the save file you want to load.

When running the command, you need to replace "${filename}" with the name of your game save file. For example, if your save file is called "mygame.sav", the command would be:

openttd -g mygame.sav

By using this command, the OpenTTD game will start and load the specified save file, allowing you to continue playing from where you left off.
