I can run a launcher that runs drracket and loads a file.  
Trying to setup a launcher that runs Racket, loads a file containing a module and calls the module. Something like following which does not work:  
drracket -l file.rkt '(run-my-module)'  
or  
racket -l file.rkt '(run-my-module)'

Thanks

file.rkt:

```scheme
#! /usr/bin/env racket

(module yourmodule racket
	
;; module code here

)

```

make it executable:

```scheme
chmod u+x file.rkt

```

run it:

```scheme
./file.rkt

```

but i'm not sure this is what you want....

`-l` only works for things like `x/y/z`, e.g. `raco/main`, and `-t` necessarily calls the `main` submodule if it exists. So I think the only option is

```scheme
racket -e '(require (submod "XYZ.rkt" YOUR-SUBMOD))'

```

or

```scheme
racket -e '(require (submod (file "~/dir/XYZ.rkt") YOUR-SUBMOD))'

```

For example, this one manually runs the `test` submodule:

```scheme
racket -e '(require (submod "mycode.rkt" test))'

```
