The command kotlin ${filename-jar} is using the Kotlin runtime to execute a jar file identified by the ${filename-jar} placeholder.

Here's a breakdown:

• kotlin: This is the command used to run Kotlin code. It is typically followed by a Kotlin file name or other relevant parameters.
• ${filename-jar}: This is a placeholder for a specific jar file. The actual name of the jar file should be substituted here. The ${filename-jar} is a variable that needs to be replaced with the actual name of the jar file you want to execute.

By running this command, the Kotlin runtime will execute the specified jar file, running the Kotlin code contained within it.
