What is that syntax : $FilePath$ -t?

The syntax $FilePath$ -t is commonly used in various contexts, such as in IDEs or text editors, to represent a placeholder that will be replaced with the actual file path when a command or action is executed.

The $FilePath$ placeholder is typically replaced with the full path of the current file being worked on. The -t part is specific to the context or tool being used, and its meaning can vary.

Without further context, it is difficult to determine the exact purpose or meaning of -t in your case. It could be an argument or option for a specific command or tool that expects a certain value. I would need more information about the specific context or tool you are referring to in order to provide a more precise explanation.
