The command racket --eval "${expression}" is used to execute a Racket expression from the command line by passing it as a parameter. Here is a breakdown of the command: - racket: This is the command to run the Racket interpreter.

• --eval: This option tells the Racket interpreter that an expression will be provided for evaluation.
• ${expression}: This is a placeholder for the Racket expression that you want to evaluate. You need to replace ${expression} with the actual Racket expression you want to run. For example, if you want to evaluate the Racket expression (displayln "Hello, World!"), you would run the command: racket --eval "(displayln \"Hello, World!\")" The Racket interpreter will execute the given expression and display the output, which in this case would be Hello, World! followed by a newline.
