[racket] Help: Running racket programs from command line

Hello Horace,

I thank you for patiently explaining me how to run racket from command line.

Actually, this is not exactly what I am looking for.

What I want is a script file. Such that I can test the modules of the
program from command prompt.

Something like

*******
#!/bin/bash
racket -f "file.rkt"

racket (twice 2)
*******

Thanks in advance,
Colum
